  • On November 8, 2011, the asteroid 2005 YU55 will be making a relatively close flyby of Earth. There is no threat of a collision between the asteroid and our planet, but its approach will provide scientists with a close-up view of a 400-meter-wide space rock.

  • New observations of '55 Cancri e' indicate that the planet is 60 percent larger in diameter than Earth, but eight times more massive. The data also indicates that 55 Cancri e orbits so close to its star that it is baked to a temperature of

  • NASA satellites have shown that an increase in the brightness of the asteroid Scheila is likely due to a collision between Scheila and a smaller asteroid. Studying the physical properties and behavior of asteroids can help us understand their potential role in the origins of

  • A new study shows that emissions from the radio aurora of Jupiter-like planets should be detectable with radio telescopes. The finding means that detecting exoplanets that orbit at large distances from their star could now be easier to find.

  • Astronomers have found that Jupiter-like worlds around other stars push shock waves ahead of them. Like Earth's magnetic 'bow-shock', these planetary 'shocks' can protect the atmospheres of giant planets from their star's damaging emissions.

  • A new analysis of the well-known Allende meteorite could change prevailing theories about the nature of some asteroids and the formation of planets like Earth. The results indicate that asteroids with molten cores may be abundant in space, and they even could have given the

  • A new study says that worlds that orbit red dwarfs, and even rogue planets with no stars to call home, might have surface oceans loaded with organic compounds. Like the seas of liquid methane on Saturn´s moon Titan, such environments are speculated to have

  • A recently discovered asteroid has been following the Earth in its motion around the Sun. The asteroid has been following us for 250,000 years and may be related to the origin of our planet.
