Ancient galaxies found in our cosmic neighborhood

The galaxies date from the so-called cosmic Dark Ages.

NASA wants to take a piece of an asteroid and make it a moon of the Moon

It almost sounds too cheesy to be true: NASA wants to send a shuttle to an asteroid, pluck a piece of it, then make it return to the Moon and orbit it. Then, brave astronauts will go and retrieve the sample, bringing it back to Earth for study. But that’s exactly what astronomers and engineers at the space agency want to do.

Astronomers discover the oldest known star

A team led by astronomers at The Australian National University has discovered what they believe to be the oldest star in the known Universe – forming shortly after the Big Bang, some 13.7 billion years ago. This is the first time astrophysicists get the chance to study the chemistry of the oldest stars, giving scientists a clearer idea of what

For the first time, researchers discover true color of distant planet

The world, known as HD189733b, has a deep azure hue, probably the result of molten silicate glass rain in the atmosphere, which scatters blue light. The giant planet is one of the closest and most studied in the exoplanets recently discovered; it is a sauna, a hazy hothouse swept by blow-torch winds powered by the molten silicates. It is most

New Experiment on to Revalidate Nobel Winning Universe Acceleration Finding

This year’s Nobel Prize winning finding that the ‘Universe is accelerating’ is being subjected to another validation test in the USA to confirm whether the expansion is “even or uneven”.   “We are testing the acceleration theory through another experiment to find whether the expansion is even or multi-directional. We are confident it would be ‘even’,” says eminent cosmologist Prof.Robert

How many Earth-like planets are there in the Milky Way? Billions, according to astronomers

One of the most outstanding dreams astronomers and other scientists hope to accomplish is to someday encounter proof that extraterestrial life exists. Intelligent life might be extremely far off, however microbiological life should without a doubt be present elsewhere other than our planet or solar system. For life to blossom, however, the right conditions have to be met, and one

Supercomputer simulation confirms Universe formation model

Astronomers at  UC Santa Cruz have set  a new benchmark for cosmological research for decades to come maybe, after successfully simulating the forming of distant galaxies, like our very own Milky Way, under the mysterious forces of dark matter and dark energy. Named Bolshoi – for the Russian word meaning “grand” or “great” – the simulation’s results are on par with what

[VIDEO] The ISS and Atlantis shuttle as seen in broad daylight

Incredibly enough, using a a simple, standard issued astrophotography set-up, amateur astronomer Scott Ferguson was able to film in incredible detail the ISS docked together with Atlantis as they both orbited above him – all in clear sky, broad daylight. How did he do this? Well, as equipment goes Scott, like I said, used a simple 20 cm (8 inch) telescope

Extrasolar hot Jupiter sheds some light on our own solar system

Since 1995, over 500 planets that don’t orbit our Sun have been discovered, with the numbers increasing more and more in the past years. But only recently did astrophysicists observe that in some of these cases, the star seems to be spinning in one direction, and the planet orbits it in the totally opposite direction – totally counterintuitive and against

Some black holes may be older than time itself

An intriguing hypothesis was brought up by Professor Bernard Carr from Queen Mary University in London and Professor Alan Coley from Canada’s Dalhousie University, who claims that some of the black holes we see today may actually be remnants of a past universe that collapsed into itself after a Big Crunch. I don’t know about you, but I’m having some

Carl Sagan’s Cosmos

In case you have no idea who Carl Sagan is… well, you should, basically. Carl Sagan is one of those men who brought science to the people, making numerous fields such as astronomy, astrophysics, exobiology, and many, many more accessible for the masses. He published more than six hundred research papers and popular science works, and reached the minds and

NASA rejects Russian report: Apophis asteroid extremely unlikely to hit earth

In 2004, NASA researchers identified the Apophis asteroid and after some quick calculations they states there is a chance the asteroid will hit our homey planet in 2029. A few observations and some other calculations later, they explained that that chance is extremely small for 2029, as well as other years to come. However, reports from Russia claim that the

Astronomers upset the theory of planetary formation

The discovery of 9 new planets raises some serious questions on the matter of how planets are formed. Two astronomers from the University of California, Santa Barbara reported the discovery, and of them, two are spinning in the opposite direction the planets in our solar system are spinning. This, along with other recent studies of exoplanets (planets outside the solar

Saturn’s moon full of geysers

There are many things we have yet to find out about Saturn, but the Cassini probe has definitely shed some light on the planet, and will surely do the same in the following years. The most recent flyby showed a significant number of geysers just waiting to pop out from under the surface – even more than previously believed. The

New planet close to size of Earth found

The Planet Researchers have long been interested in finding other planets that have approximately the same size as our mother earth, because it’s estimated that they have the biggest odds of hosting life in a significant diversity. However, out of the over 400 planets that have been discovered so far, the vast majority resembles Jupiter rather than Earth. Scientists using

‘Fossil’ fireballs found from supernovae

The US-Japan Sukazu observatory reported the finding of some never-before seen embers from the high temperature fireballs that immediately follower the supernovae explosions. Even after thousands of years in which they haven’t been exposed to any heat source, gas within these stellar wrecks is 10.000 hotter than the Sun’s surface. “This is the first evidence of a new type of

The symphony of science

I was quite stunned to stumble across this video. As the name says, it’s a… well it’s not quite a symphony, but it’s definitely musical, and you can definitely learn a lot of things, or re-hear them in an unique way, if you already know them. Did I mention it’s featuring Carl Sagan, Richard Feynman, Neil deGrasse Tyson & Bill

Water and fog found on Titan, Saturn’s moon

As I was writing in a previous post, Titan is quite unique, in that aside from our planet it’s the only place in our solar system where significant quantities of liquid are to be found (though most are liquid ethane and methane). That doesn’t seem to make much of a difference considering the chemistry of it, but according to astronomer

Stellar ‘cannibalism’ is the key to giant stars

You may or may not have heard about blue stragglers; they are blue stars that are hotter and bluer than other stars with the same luminosity. Until now, it seemed that these stars defied most if not all of the standard stellar theories, but scientists now believe they have finally solved this stellar mistery. The research carried out by the
