7:11 PM | Tatooine-Like Planets May Be More Common Than We Thought
For decades, astronomers have assumed that Earth-like planets cannot form around binary stars on account of wacky gravitational effects. Which, for Star Wars fans, was a total downer. But a new study suggests that not only is the formation of Tatooine-like planets very much possible, they may actually be quite common. Read more...

11:33 AM | Astronomers Discover Over 200 Young Galactic Clusters in Distant Cosmos
An international team of astronomers using data from two ESA’s space telescopes, Planck and Herschel, has identified more than 200 proto-clusters of galaxies in the distant Universe, many of which were magnified by other galaxies lying in front of them via gravitational lensing. Galaxies like our own are usually not found in isolation. In the [...]

10:06 PM | Falling stones paint it black
Mercury is the smallest planet in the Solar System, but some of its properties are a big challenge to explain. Today's Astrobite presents a solution to one of these issues: The darkening of Mercury is induced by a high abundance of carbon delivered by meteorites.

8:54 PM | As stars form, magnetic fields influence regions big and small
Stars form when gravity pulls together material within giant clouds of gas and dust. But gravity isn’t the only force at work. Both turbulence and magnetic fields battle gravity, either […]

8:39 PM | More evidence for groundwater on Mars
Scientists investigated the Equatorial Layered Deposits (ELDs) of Arabia Terra in Firsoff crater area, Mars, to understand their formation and potential habitability. On the plateau, ELDs consist of rare mounds, […]

8:36 PM | Dark matter even darker than once thought
Astronomers have studied how dark matter in clusters of galaxies behaves when the clusters collide. The results show that dark matter interacts with itself even less than previously thought, and […]

8:32 PM | Supermassive Black Hole Blasts Star-Making Gas From Galaxy’s Core
Many galaxies blast outward from their centers huge, wide-angled flows of material — pushing to their outer edges enough dust and gas each year to otherwise have formed more than […]

8:20 PM | ALMA disentangles complex birth of giant stars
Astronomers have conducted observations of the massive-star forming region IRAS 16547-4247. The observation results shows the presence of multiple, or at least two, gas outflows from a protostar, indicating the […]

7:53 PM | Why Did A Group Of Medieval Monks See Part Of The Moon Explode?
In 1178, a group of monks at Canterbury saw the moon suddenly explode into sparks, "writhe," and "take on a blackish appearance." What the hell did they see? Read more...

3:21 PM | A hundred times NO – the moon does not cause a crazy night at the hospital
Yet another analysis has come out to kill the idea that hospital admissions and human birth rates are greater during the full moon than at other times. More than one analysis of such data shows conclusively that the moon has no correlation with these conditions. But, it’s such a widespread belief, I’m not sure another study… Source: Doubtful News Related posts:Ask an astrobiologist about the 2012 Doomsdate The Big Bad Moon, used to sell fear to the superstitious […]

1:06 AM | Astroquizzical: Do all planets rotate in orbit around their stars? (Synopsis)
When you think about our world and our place in the Solar System, you very likely think about Earth, spinning on its axis, with the Moon orbiting around it, and with the entire Earth-Moon system orbiting the Sun. But did you know that all of it — the Earth spinning on its axis, the Moon revolving around…

4:35 PM | Gorgeous New Image from Hubble Space Telescope Shows Spiral Galaxy NGC 3021
Astronomers using the Advanced Camera for Surveys (ACS) on the NASA/ESA Hubble Space Telescope have captured a stunning new image of the spiral galaxy NGC 3021. NGC 3021, also known as UGC 5280 or SDSS J095057.14+333313.0, is approximately 100 million light-years away in the direction of the constellation Leo Minor. Among many other types of [...]

2:59 PM | Astronomers See Supermassive Black Hole in Action
A team of astronomers, led by Dr Francesco Tombesi of NASA’s Goddard Space Flight Center and the University of Maryland, has observed two related phenomena in the same galaxy, IRAS F11119+3257: a huge galactic outflow, seen by ESA’s Herschel Space Observatory, and a black-hole driven wind at the galaxy’s center, detected with the Suzaku X-ray [...]

9:43 AM | Rocky Exoplanets around Binary Stars May Be Widespread, Astrophysicists Say
According to astrophysicists Dr Scott Kenyon of the Smithsonian Astrophysical Observatory and Dr Ben Bromley of the University of Utah, terrestrial, Earth-like exoplanets around binary stars may be common. For years, scientists believed that rocky planets could not form around most binary stars, at least not close enough to support life. The problem is that [...]

A group of astronomers headed by Dr Andreas Eckart from the University of Cologne, Germany, has made the best observations so far of a dusty red object at the Milky Way’s galactic center, known as G2, using the SINFONI instrument on the European Southern Observatory’s Very Large Telescope (VLT) in Chile. According to the group, [...]

12:05 PM | Dark Matter Collisions
The existence of dark matter is one of the coolest science stories of my lifetime. When I was growing up I was in love with pretty much every field of science, but particularly with astronomy, and at that time we had no idea that 85% of the matter in the universe even existed. We now [...]

9:40 PM | On Friday, asteroid 2014-YB35 is expected to make its closest approach to Earth.
On Friday, asteroid 2014-YB35 is expected to make its closest approach to Earth. Traveling at over 23,000 mph (37,000 km/h), NASA says the 6.2 mile (1,000 meter) asteroid won't get any closer than 2.7-million miles (4.4 million km). That's nearly 12 times the distance from Earth to the Moon – so relax.Read more...
