NGC 253 is one of the brightest spiral galaxies in the sky

Astronomers from the Instituto de Astrofísica de Canarias (Spain) used NACO, a sharp-eyed adaptive optics instrument on ESO’s Very Large Telescope (VLT), to study the fine detail in NGC 253, one of the brightest and dustiest spiral galaxies in the sky.

Over 200 Extra planets being formed

Two independent groups have simultaneously made the first-ever ground-based detection of extrasolar planets thermal emissions. Until now, virtually everything known about atmospheres of planets orbiting other stars in the Milky Way has come from space-based observations.

XMM-Newton Measures Speedy Spin Of Rare Celestial Object

XMM-Newton has caught the fading glow of a tiny celestial object, revealing its rotation rate for the first time. The new information confirms this particular object as one of an extremely rare class of stellar zombie – each one the dead heart of a star that refuses to die.

New Laser Probe Developed For Space Program Could Spot Cataracts Earlier

New Laser Probe Developed For Space Program Could Spot Cataracts Earlier 

 A beam of light from a slit-lamp microscope focused on a cataract.

Cataracts are the single biggest cause of blindness and are responsible for almost half of all cases worldwide. A new laser probe, originally developed for the U.S. space program, has been shown to detect the condition earlier than is otherwise possible. Its developers say that the technique can tell that a cataract is forming even when an eye looks perfectly clear.

Lunar Bricks Could Be Used To Build Bases On The Moon

Lunar Bricks Could Be Used To Build Bases On The Moon 

Most of the concepts for lunar bases we tend to see are dome-shaped, built locally here on Earth and then transported. The “Masons of Regolith,” a team of seven Virginia Tech students named for the rock that is present on the Earth, the Moon and asteroids, think that those domes could be built on the lunar surface instead, made from rock gathered on site.

New galaxies… Life sustaining?

An ongoing X-ray survey undertaken by NASA’s Swift spacecraft is revealing differences between nearby active galaxies and those located about halfway across the universe. Understanding these differences will help clarify the relationship between a galaxy and its central black hole.

How Martian Winds Make Rocks Walk

Is there any way i can buy those red shoes?

At first, figuring out how pebble-sized rocks organize themselves in evenly-spaced patterns in sand seemed simple and even intuitive. But once Andrew Leier, an assistant geoscience professor at the U of C, started observing, he discovered that the most commonly held notions did not apply.
