Far Flung Star Cluster Found at Milky Way’s Edge

Astronomers in Brazil have discovered a cluster of stars forming at the edge of the Milky Way, according to a press release from the Royal Astronomical Society.




Excerpt from  news.discovery.com


This is unusual because it was believed that stars generally take form closer to the center of our spiral-shaped galaxy, rather than from its swirling, spiral arms, which are thousands of light-years away. These two clusters of stars — named Camargo 438 and 439 — were seen in a cloud at the galaxy’s outskirts.

Denilso Camargo, an astronomer at the Federal University of Rio Grande do Sul in Porto Alegre, Brazil, led a team that analyzed data from NASA’s orbiting Wide-Field Infrared Survey Explorer (WISE) observatory. They zeroed in on dense clumps of gas in so-called giant molecular clouds(GMCs) that are known to generate stars. GMCs are mainly located in the inner part of the galactic disc.

The new star clusters lie about 16,000 light-years away from the main disk of the Milky Way galaxy. How did they form there? The scientists aren’t yet sure but Camargo theorizes that one of two scenarios could have led to the stars’ formation.

In the first scenario, called the “chimney model,” supernovas could have flung the gas and dust that formed the cloud out of the Milky Way. Another explanation is the material could have drifted in from outside the galaxy.


“Our work shows that the space around the Galaxy is a lot less empty that we thought,” said Camargo. “The new clusters of stars are truly exotic.”

Camargo’s team published their results in the journal Monthly

Is This a Baby Picture of a Giant Planet?

Excerpt from news.discovery.com


Mommy, where do baby planets come from? There’s no storks, birds, bees, or romantic dinners for two involved in the answer to that question — regardless of size, planets are all formed in pretty much the same way: through the aggregation of material within the disk of dust and gas surrounding a young star. While how long it actually takes and just what sort of planets are most likely to form where are still topics of discussion among astronomers, the birth process of a planet is fairly well understood.

And this may be the very first image of it actually happening.

Acquired by the European Southern Observatory’s Very Large Telescope (VLT), the infrared image above (right) shows a portion of the disk of gas and dust around the star HD100546, located 335 light-years away in the constellation Musca. By physically blocking out the light from the star itself by means of an opaque screen — seen along the left side of the image — the light from the protoplanetary disk around HD 100546 can be seen, revealing a large bright clump that’s thought to be a planet in the process of formation.

If it is indeed a baby planet, it’s a big one — as large as, or perhaps even larger than, Jupiter.

This does raise an interesting question for astronomers because if it is a Jupiter-sized planet, it’s awfully far from its star… at least according to many current models of planetary formation. About 68 times as far from HD100546 as we are from the sun, if this planet were in our solar system it’d be located deep in the Kuiper Belt, twice as far as Pluto. That’s not where one would typically expect to find gas giants, so it’s been hypothesized that this protoplanet might have migrated outwards after initially forming closer to the star… perhaps “kicked out” by gravitational interaction with an even more massive planet.

Alternatively, it may not be a planet at all — the bright blob in the VLT image might be coming from a much more distant source. While extremely unlikely, further research will be needed to rule that possibility out.

If it’s found to be a planet, HD100546 “b” would offer scientists an unprecedented opportunity to observe a planetary formation process in action — and from a relatively close proximity as well.

According to the team’s paper, submitted to Astrophysical Journal Letters, ”What makes HD100546 particularly interesting is that 1. it would be the first imaged protoplanet that is still embedded in the gas and dust disk of its host star; and 2. it would show that planet formation does occur at large orbital separations.”

(Now all we have to do is wait a couple billion years and then show these pictures to HD100546b’s girlfriend. How embarrassing!)

Partial Solar Eclipse Thursday ~ Next Eclipse Not Until 2017

Excerpt from usatoday.com

Don't forget to look up Thursday.

In the afternoon, a partial solar eclipse — where the moon covers a part of the sun — will be visible across much of the USA, barring any pesky clouds that could block the show. 

The eclipse will occur over most of North America — except for a small slice of eastern Canada and eastern New England, said meteorologist Joe Rao of Space.com.


In most of the eastern half of the USA and Canada, the eclipse will still be in progress at sunset — offering dramatic views if you can find a low western horizon, according to Sky and Telescope. In New York City, the eclipse starts at 5:49 p.m. ET and will last until the sun sets at 6:03 p.m. ET.

However, "people who live east of a line running from roughly Quebec City to Montauk Point, N.Y., will miss out on the solar show, since the sun will set before the dark disc of the moon begins to encroach upon it," Rao said.


During a solar eclipse, the sun, moon and Earth form a nearly straight line, with the moon in the middle. The moon temporarily blocks the sun in select areas on Earth.
Unless you use a special filter, such as welder's glasses, never look directly at the sun during the eclipse, or at any time for that matter. Universe Today warns that dangerous ultraviolet and infrared light focused on your retinas will damage your vision for the rest of your life.

Your camera also needs a special filter in order to photograph the eclipse.

The USA's next solar eclipse — which will be a total eclipse — won't occur until August 2017.

500 Exocomets Found Orbiting Nearby Star Beta Pictoris

French astronomers using the HARPS instrument on the ESO 3.6-m telescope at the La Silla Observatory in Chile have discovered nearly 500 comets around the nearby star Beta Pictoris and have found that they belong to two distinct families: old comets that have made multiple passages near the star, and younger comets that probably came from the recent breakup of one or more larger objects.

Beta Pictoris is a young star located about 63 light-years from Earth. It is only about 20 million years old and is surrounded by a huge disc of material.

For almost three decades, astronomers have seen subtle changes in the light from this star that were thought to be caused by the passage of comets in front of the star itself.


The analysis revealed the presence of two distinct families of exocomets: one family of old exocomets whose orbits are controlled by a massive planet, and another family, probably arising from the recent breakdown of one or a few bigger objects. Different families of comets also exist in our Solar System.


“For the first time a statistical study has determined the physics and orbits for a large number of exocomets. This work provides a remarkable look at the mechanisms that were at work in the Solar System just after its formation 4.5 billion years ago,” concluded Dr Kiefer, who is the first author of the paper published in the journal Nature.

Black holes do NOT exist and the Big Bang Theory is wrong, claims scientist – and she has the maths to prove it




dailymail.co.uk

By Jonathan O’Callaghan

  • Scientist claims she has mathematical proof black holes cannot exist
  • She said it is impossible for stars to collapse and form a singularity
  • Professor Laura Mersini-Houghton said she is still in 'shock' from the find
  • Previously, scientists thought stars much larger than the sun collapsed under their own gravity and formed black holes when they died
  • During this process they release a type of radiation called Hawking radiation
  • But new research claims the star would lose too much mass and wouldn't be able to form a black hole
  • If true, the theory that the universe began as a singularity, followed by the Big Bang, could also be wrong

  • When a huge star many times the mass of the sun comes to the end of its life it collapses in on itself and forms a singularity – creating a black hole where gravity is so strong that not even light itself can escape.
    At least, that’s what we thought.
    A scientist has sensationally said that it is impossible for black holes to exist – and she even has mathematical proof to back up her claims.
    If true, her research could force physicists to scrap their theories of how the universe began.
    A scientist from University of North Carolina states she has mathematical proof that black holes (illustrated) can't exist. She said it is impossible for stars to collapse and form a singularity. Previously, scientists thought stars  larger than the sun collapsed under their own gravity and formed black holes as they died

    A scientist from University of North Carolina states she has mathematical proof that black holes (illustrated) can’t exist. She said it is impossible for stars to collapse and form a singularity. Previously, scientists thought stars larger than the sun collapsed under their own gravity and formed black holes as they died
    The research was conducted by Professor Laura Mersini-Houghton from the University of North Carolina at Chapel Hill in the College of Arts and Scientists.

    She claims that as a star dies, it releases a type of radiation known as Hawking radiation – predicted by Professor Stephen Hawking.

    THE BLACK HOLE INFORMATION PARADOX

    One of the biggest unanswered questions about black holes is the so-called information paradox.
    Under current theories for black holes it is thought that nothing can escape from the event horizon around a black hole – not even light itself.
    Inside the black hole is thought to be a singularity where matter is crushed to an infinitesimally small point as predicted by Einstein’s theory of gravity.
    However, a fundamental law of quantum theory states that no information from the universe can ever disappear.
    This creates a paradox; how can a black hole make matter and information ‘disappear’?
    Professor Mersini-Houghton’s new theory manages to explain why this might be so – namely because black holes as we know them cannot exist.
    However in this process, Professor Mersini-Houghton believes the star also sheds mass, so much so that it no longer has the density to become a black hole.
    Before the black hole can form, she said, the dying star swells and explodes.
    The singularity as predicted never forms, and neither does the event horizon – the boundary of the black hole where not even light can escape.
    ‘I’m still not over the shock,’ said Professor Mersini-Houghton.
    ‘We’ve been studying this problem for a more than 50 years and this solution gives us a lot to think about.’
    Experimental evidence may one day provide physical proof as to whether or not black holes exist in the universe.
    But for now, Mersini-Houghton says the mathematics are conclusive.
    What’s more, the research could apparently even call into question the veracity of the Big Bang theory.
    Most physicists think the universe originated from a singularity that began expanding with the Big Bang about 13.8 billion years ago.
    If it is impossible for singularities to exist, however, as partially predicted by Professor Mersini-Houghton, then that theory would also be brought into question.

    THIS is what a black hole looks like – simulation shows disc…
    During the collapse process stars release a type of radiation called Hawking radiation (shown). But Professor Mersini-Houghton claims this process means the star loses too much mass and can't form a black hole. And this also apparently means the Big Bang theory, that the universe began as a singularity, may not be correct

    THERE ARE NO BLACK HOLES, ONLY GREY HOLES, CLAIMS HAWKING

    Earlier this year Professor Stephen Hawking shocked physicists by saying ‘there are no black holes’.
    In a paper published online, Professor Hawking instead argues there are ‘grey holes’
    ‘The absence of event horizons means that there are no black holes – in the sense of regimes from which light can’t escape to infinity,’ he says in the paper, called Information Preservation and Weather Forecasting For Black Holes.
    He says that the idea of an event horizon, from which light cannot escape, is flawed.
    He suggests that instead light rays attempting to rush away from the black hole’s core will be held as though stuck on a treadmill and that they can slowly shrink by spewing out radiation.
    One of the reasons black holes are so bizarre is that they pit two fundamental theories of the universe against each other.
    Namely, Einstein’s theory of gravity predicts the formation of black holes. But a fundamental law of quantum theory states that no information from the universe can ever disappear.
    Efforts to combine these two theories proved problematic, and has become known as the black hole information paradox – how can matter permanently disappear in a black hole as predicted?
    Professor Mersini-Houghton’s new theory does manage to mathematically combine the two fundamental theories, but with unwanted effects for people expecting black holes to exist.
    ‘Physicists have been trying to merge these two theories – Einstein’s theory of gravity and quantum mechanics – for decades, but this scenario brings these two theories together, into harmony,’ said Professor Mersini-Houghton.
    ‘And that’s a big deal.’
