New research shows Universe expansion pace isn’t as fast as assumed earlier



universe


Excerpt from thewestsidestory.net

The Universe is expanding and any student of astronomy will vouch to this fact. However according to a team of astronomers the acceleration of the universe may not be as quick as it was assumed earlier.

A team of astronomers have discovered that certain types of supernova are more varied than earlier thought of and in the process have led to the biggest mystery of the universe-how fast is the universe expanding after the big bang?

Peter A. Milne of the University of Arizona said, “We found that the differences are not random, but lead to separating Ia supernovae into two groups, where the group that is in the minority near us are in the majority at large distances — and thus when the universe was younger, there are different populations out there, and they have not been recognized. The big assumption has been that as you go from near to far, type Ia supernovae are the same. That doesn’t appear to be the case.”
The discovery throws new light on the currently accepted view of the universe expanding at a faster and faster rate pulled apart by an unknown force called dark energy this observation resulted in 2011 Nobel Prize for Physics.
Milne said, “The idea behind this reasoning, is that type Ia supernovae happen to be the same brightness — they all end up pretty similar when they explode. Once people knew why, they started using them as mileposts for the far side of the universe.The faraway supernovae should be like the ones nearby because they look like them, but because they’re fainter than expected, it led people to conclude they’re farther away than expected, and this in turn has led to the conclusion that the universe is expanding faster than it did in the past.”
The researchers felt that the accelerating universe can be explained on the basis of color difference in between two groups of supernova leaving less acceleration than earlier assumed and in the process will require lesser dark energy.

Milne said, “We’re proposing that our data suggest there might be less dark energy than textbook knowledge, but we can’t put a number on it, until our paper, the two populations of supernovae were treated as the same population. To get that final answer, you need to do all that work again, separately for the red and for the blue population.

Type la supernovae are considered as a benchmark for far away sources of light they do have a fraction of variability which has limited our knowledge of the size of the universe.
The distance of objects with the aid of our binocular vision and the best space-based telescopes and most sophisticated techniques works out in the range of ten or twenty thousand light years. 
However as compared to the vastness of space, this is just pea nuts.
For Distances greater than that it is imperative to compare the absolute and observed brightness of well understood objects and to use the difference to determine the object’s distance.

In astronomy it is difficult to find an object of known brightness since there are examples of both bright and dim stars and galaxies. However there is one event which can be used to work out its absolute brightness. Supernovas are the final stages of a dying star and it explodes with such violence, the flash can be seen across the vast universe.

Type la Supernovae occurs in a binary star system when a white dwarf scoops off mass from its fellow star. This reproducible mechanism gives a well determined brightness and therefore scientists term such Type la supernovae as ‘standard candles’.

Astronomers found that the Type la supernovae is so uniform that it has been designated as cosmic beacons and used to assess the depths of the universe. It is now revealed that they fall into different populations and are not very uniform as previously thought. .

This is the most crystal-clear image of space ever taken ~ Video



Cropped from full photo of Andromeda galaxy taken by the Hubble telescope. 


Excerpt from qz.com

The vastness of space is so expansive, so inconceivable, that frankly, it makes humanity’s lot in the universe seem pretty tiny and pointless.

Amplifying that sense of insignificance, NASA has released its largest, most detailed image of space ever. Taken by the Hubble Space Telescope, it captures the Andromeda Galaxy, one of our nearest galactic neighbors at a mere 2.5 million light years away.
The full size image is about 60,000 by 22,000 pixels, a total of 1.5 billion pixels. That’s about 1,000 times the resolution of regular high-definition. It is detailed enough that the telescope can resolve individual stars in the 61,000 light year-long slice of galaxy captured by the image—”like photographing a beach and resolving individual grains of sand,” according to NASA. All in all, there are over 100 million stars in the photo. (See video)
And indeed, zooming in on the image does make it look like a close-up of a beach:

Top 6 tips for using ordinary binoculars for stargazing




Excerpt from earthsky.org


Admit it.  You’ve probably got a pair of binoculars lying around your house somewhere. They may be perfect – that’s right, perfect – for beginning stargazing. Follow the links below to learn more about the best deal around for people who want to get acquainted with the night sky: a pair of ordinary binoculars.
1. Binoculars are a better place to start than telescopes
2. Start with a small, easy-to-use size
3. First, view the moon with binoculars.
4. Move on to viewing planets with binoculars.
5. Use your binoculars to explore inside our Milky Way.
6. Use your binoculars to peer beyond the Milky Way.

1. Binoculars are a better place to start than telescopes. The fact is that most people who think they want to buy a telescope would be better off using binoculars for a year or so instead.  That’s because first-time telescope users often find themselves completely confused – and ultimately put off – by the dual tasks of learning the use a complicated piece of equipment (the ‘scope) while at the same time learning to navigate an unknown realm (the night sky).
Beginning stargazers often find that an ordinary pair of binoculars – available from any discount store – can give them the experience they’re looking for.  After all, in astronomy, magnification and light-gathering power let you see more of what’s up there.  Even a moderate form of power, like those provided by a pair of 7×50 binoculars, reveals 7 times as much information as the unaided eye can see.

You also need to know where to look. Many people start with a planisphere as they begin their journey making friends with the stars. You can purchase a planisphere at the EarthSky store. Also consider our Astronomy Kit, which has a booklet on what you can see with your binoculars.

2. Start with a small, easy-to-use size.  Don’t buy a huge pair of binoculars to start with! Unless you mount them on a tripod, they’ll shake and make your view of the heavens shakey, too. The video above – from ExpertVillage – does a good job summing up what you want. And in case you don’t want to watch the video, the answer is that 7X50 binoculars are optimum for budding astronomers.  You can see a lot, and you can hold them steadily enough that jitters don’t spoil your view of the sky.  Plus they’re very useful for daylight pursuits, like birdwatching. If 7X50s are too big for you – or if you want binoculars for a child – try 7X35s.

3. First, view the moon with binoculars. When you start to stargaze, you’ll want to watch the phase of the moon carefully. If you want to see deep-sky objects inside our Milky Way galaxy – or outside the galaxy – you’ll want to avoid the moon. But the moon itself is a perfect target for beginning astronomers, armed with binoculars. Hint: the best time to observe the moon is in twilight. Then the glare of the moon is not so great, and you’ll see more detail.

You’ll want to start your moon-gazing when the moon is just past new – and visible as a waxing crescent in the western sky after sunset. At such times, you’ll have a beautiful view of earthshine on the moon.  This eerie glow on the moon’s darkened portion is really light reflected from Earth onto the moon’s surface.  Be sure to turn your binoculars on the moon at these times to enhance the view. 
Each month, as the moon goes through its regular phases, you can see the line of sunrise and sunset on the moon progress across the moon’s face. That’s just the line between light and dark on the moon. This line between the day and night sides of the moon is called the terminator line.  The best place to look at the moon from Earth – using your binoculars – is along the terminator line. The sun angle is very low in this twilight zone, just as the sun is low in our sky around earthly twilight.  So, along the terminator on the moon, lunar features cast long shadows in sharp relief.

You can also look in on the gray blotches on the moon called maria, named when early astronomers thought these lunar features were seas.  The maria are not seas, of course, and instead they’re now thought to have formed 3.5 billion years ago when asteroid-sized rocks hit the moon so hard that lava percolated up through cracks in the lunar crust and flooded the impact basins. These lava plains cooled and eventually formed the gray seas we see today.

The white highlands, nestled between the maria, are older terrain pockmarked by thousands of craters that formed over the eons. Some of the larger craters are visible in binoculars. One of them, Tycho, at the six o’clock position on the moon, emanates long swatches of white rays for hundreds of miles over the adjacent highlands. This is material kicked out during the Tycho impact 2.5 million years ago.

4. Move on to viewing planets with binoculars. Here’s the deal about planets.  They move around, apart from the fixed stars.  They are wanderers, right?

You can use our EarthSky Tonight page to locate planets visible around now.  Notice if any planets are mentioned in the calendar on the Tonight page, and if so click on that day’s link.  On our Tonight page, we feature planets on days when they’re easily identifiable for some reason – for example, when a planet is near the moon.  So our Tonight page calendar can help you come to know the planets, and, as you’re learning to identify them, keep your binoculars very handy. Binoculars will enhance your view of a planet near the moon, for example, or two planets near each other in the twilight sky. They add a lot to the fun!

Below, you’ll find some more simple ideas on how to view planets with your binoculars.

Mercury and Venus. These are both inner planets.  They orbit the sun closer than Earth’s orbit.  And for that reason, both Mercury and Venus show phases as seen from Earth at certain times in their orbit – a few days before or after the planet passes between the sun and Earth.  At such times,  turn your binoculars on Mercury or Venus. Good optical quality helps here, but you should be able to see them in a crescent phase. Tip: Venus is so bright that its glare will overwhelm the view. Try looking in twilight instead of true darkness.

Mars. Mars – the Red Planet – really does look red, and using binoculars will intensify the color of this object (or of any colored star). Mars also moves rapidly in front of the stars, and it’s fun to aim your binoculars in its direction when it’s passing near another bright star or planet.

Jupiter. Now on to the real action!  Jupiter is a great binocular target, even for beginners.   If you are sure to hold your binoculars steadily as you peer at this bright planet,  you should see four bright points of light near it.  These are the Galilean Satellites – four moons gleaned through one of the first telescopes ever made, by the Italian astronomer Galileo. Note how their relative positions change from night to night as each moon moves around Jupiter in its own orbit.

Saturn.Although a small telescope is needed to see Saturn’s rings, you can use your binoculars to see Saturn’s beautiful golden color.  Experienced observers sometimes glimpse Saturn’s largest moon Titan with binoculars.  Also, good-quality high-powered binoculars – mounted on a tripod – will show you that Saturn is not round.  The rings give it an elliptical shape.

Uranus and Neptune. Some planets are squarely binocular and telescope targets. If you’re armed with a finder chart, two of them, Uranus and Neptune, are easy to spot in binoculars. Uranus might even look greenish, thanks to methane in the planet’s atmosphere. Once a year, Uranus is barely bright enough to glimpse with the unaided eye . . . use binoculars to find it first. Distant Neptune will always look like a star, even though it has an atmosphere practically identical to Uranus.

There are still other denizens of the solar system you can capture through binocs. Look for the occasional comet, which appears as a fuzzy blob of light. Then there are the asteroids – fully 12 of them can be followed with binoculars when they are at their brightest. Because an asteroid looks star-like, the secret to confirming its presence is to sketch a star field through which it’s passing. Do this over subsequent nights; the star that changes position relative to the others is our solar system interloper.

5. Use your binoculars to explore inside our Milky Way.  Binoculars can introduce you to many members of our home galaxy. A good place to start is with star clusters that are close to Earth. They cover a larger area of the sky than other, more distant clusters usually glimpsed through a telescope.

Beginning each autumn and into the spring, look for a tiny dipper-like cluster of stars called the Pleiades.  The cluster – sometimes also called the Seven Sisters – is noticeable for being small yet distinctively dipper-like. While most people say they see only six stars here with the unaided eye, binoculars reveal many more stars, plus a dainty chain of stars extending off to one side. The Pleiades star cluster is looks big and distinctive because it’s relatively close – about 400 light years from Earth. This dipper-shaped cluster is a true cluster of stars in space.  Its members were born around the same time and are still bound by gravity.  These stars are very young, on the order of 20 million years old, in contrast to the roughly five billion years for our sun.

Stars in a cluster all formed from the same gas cloud. You can also see what the Pleiades might have like in a primordial state, by shifting your gaze to the prominent constellation Orion the Hunter. Look for Orion’s sword stars, just below his prominent belt stars. If the night is crisp and clear, and you’re away from urban streetlight glare, unaided eyes will show that the sword isn’t entirely composed of stars. Binoculars show a steady patch of glowing gas where, right at this moment, a star cluster is being born. It’s called the Orion Nebula. A summertime counterpart is the Lagoon Nebula, in Sagittarius the Archer.

With star factories like the Orion Nebula, we aren’t really seeing the young stars themselves. They are buried deep within the nebula, bathing the gas cloud with ultraviolet radiation and making it glow. In a few tens of thousands of years, stellar winds from these young, energetic stars will blow away their gaseous cocoons to reveal a newly minted star cluster.

Scan along the Milky Way to see still more sights that hint at our home galaxy’s complexity. First, there’s the Milky Way glow itself; just a casual glance through binoculars will reveal that it is still more stars we can’t resolve with our eyes . . . hundreds of thousands of them. Periodically, while scanning, you might sweep past what appears to be blob-like, black voids in the stellar sheen. These are dark, non-glowing pockets of gas and dust that we see silhouetted against the stellar backdrop. This is the stuff of future star and solar systems, just waiting around to coalesce into new suns.

6. Use your binoculars to view beyond the Milky Way.  Let’s leap out of our galaxy for the final stop in our binocular tour. Throughout fall and winter, she reigns high in the sky during northern hemisphere autumns and winters: Andromeda the Maiden. Centered in the star pattern is an oval patch of light, readily visible to the unaided eye away from urban lights. Binoculars will show it even better.

It’s a whole other galaxy like our own, shining across the vastness of intergalactic space. Light from the Andromeda Galaxy has traveled so far that it’s taken more than 2 million years to reach us.
Two smaller companions visible through binoculars on a dark, transparent night are the Andromeda Galaxy’s version of our Milky Way’s Magellanic Clouds. These small, orbiting, irregularly-shaped galaxies that will eventually be torn apart by their parent galaxy’s gravity.

Such sights, from lunar wastelands to the glow of a nearby island universe, are all within reach of a pair of handheld optics, really small telescopes in their own right: your binoculars.

John Shibley wrote the original draft of this article, years ago, and we’ve been expanding it and updating it ever since. Thanks, John!
Bottom line: For beginning stargazers, there’s no better tool than an ordinary pair of binoculars. This post tells you why, explains what size to get, and gives you a rundown on some of the coolest binoculars sights out there: the moon, the planets, inside the Milky Way, and beyond. Have fun!

Has Amelia Earhart’s plane finally been found? Not so fast


 


Excerpt from

A small group of wreckage hunters purports to have found a bit of Earhart’s Lockheed Electra aircraft. It’s a good story, but critics of the find are more vocal than ever.


A metal sheet, some small bones and an “ointment pot” may be the final artifacts of Amelia Earhart’s failed 1937 journey around the world, if a small group of wreckage hunters is to be believed. They could also be the remains of some other plane, a turtle and trash. 

But the International Group for Historic Aircraft Recovery (Tighar), which first found the warped bit of aluminum on a 1991 trip to the tiny atoll of Nikumaroro, in the Republic of Kiribati, says the 19in-by-23in slab has to be part of Earhart’s Lockheed Electra aircraft, which disappeared while she was flying over the Pacific. 

Tighar’s executive director Ric Gillespie made headlines this week by announcing “new research” into the 1991 fragment that he says answers earlier critics and proves it is from Earhart’s plane. 

The story he proposes is not implausible: the metal’s rivets don’t match with the Electra’s design, but that’s because because it’s actually a patch made to repair the aircraft after a bad landing in Miami, earlier on Earhart’s trip. Gillespie’s team managed to find a Miami Herald photo from 1937 which shows, over the place where a window should be, a particularly shiny piece of metal. In fact, a lab tested the metal back in 1996 and found it to be “essentially the same” 24ST Alclad aluminum that was to cover most aircraft of the 30s, including Earhart’s Electra. Gillespie says that “the patch was as unique to her particular aircraft as a fingerprint is to an individual … [the aluminum] matches that fingerprint in many respects”.

Under Gillespie’s theory, Earhart made it to the island, sent radio signals “for at least five nights before the Electra was washed into the ocean”, and eventually died there.

But Gillsepie’s been here before, and his critics are not quiet, with one saying: “Everybody should have facts to back up [their] opinions, and Mr Gillespie, well, he doesn’t.” (A second, more concisely, says: “He’s very creative.”) After discovering the metal, Gillespie gave a 1992 press conference to say that “every possibility has been checked, every alternative eliminated … We found a piece of Amelia Earhart’s aircraft.”

Objectors immediately pointed out that he had not checked the fragment’s rivets, which did not match Earhart’s Electra. Now, 22 years later, the photo could indeed explain the discrepancy – but Gillespie still lacks a wreck to compare the pattern to. As a substitute, Gillespie’s team went to a Kansas facility that’s restoring an Electra and claims to have found – by holding the patch up alongside the restored plane – that the rivets seemed consistent with the pattern. No independent researchers have confirmed their findings.

To be fair, Tighar realizes they know less about the scrap than they’d like: “If the artifact is not the scab patch from NR16020, then it is a random piece of aircraft wreckage from some unknown type involved in an unknown accident that just happens to match the dozens of material and dimensional requirements of the patch.”

Considering the vastness of the Pacific Ocean and the sheer amount of wreckage scattered across it over the past century, this actually seems pretty reasonable, but Tighar doubles down on its implication of certainty: “[That would mean] this incredibly specific, but random, piece of debris just happened to end up on Nikumaroro, the atoll where so much other evidence points to Earhart.”

What evidence does Tighar present? In 2011 they tested three bones found near a turtle shell, which could perhaps have been human or that of a turtle. DNA tests were inconclusive. (Gillespie says “the door is still open for it to be a human finger bone.”)

Gillespie told the Miami Herald earlier this year that “the key to it is her final message, where she says ‘line of position 157 dash 337’ … That’s a line that Noonan calculated from the sunrise, running 337 degrees to the north-west and 157 degrees to the south-east. And if you follow it far enough, there are two deserted islands on it, McKeon Island and Gardner Island.” 

It’s a good story, just like the one ex-marine Floyd Kilts used to tell about how a tribesman told him about a partial human skeleton and a woman’s shoe, which ended up with a British official and disappeared afterward. (Micronesians settled on the island a year after Earhart vanished.) But despite all the story and circumstantial evidence, no expedition in the past 70 years has found the Electra on or near either island.

But Tighar of course thinks it might. It found a “sonar streak” 600ft below the surface “the right size, the right shape … in the right place to be part of the Electra”, which the group has so far had neither the time nor funding to investigate. Gillespie admits it could also be part of a reef, a geological formation or any number of things once lodged into the seabed and now drifted away. He intends to explore the site in a 2015 expedition. Whether he turns up with Earhart’s lost Electra or something else entirely, he will have a new story.
