Where are the other `Earths` beyond the Solar System?
One of the most fascinating areas of astronomical research in recent years has been the search for other `Earths` circling Sun-like stars far beyond our Solar System. In recent years nearly 100 planets have been discovered in orbits around other stars, but none of these `exoplanets` remotely resembles the Earth. However, according to the latest... view more...

Astonomers find tiny planet orbiting tiny star
An international team of astronomers led by David Bennett of the University of Notre Dame has discovered an extra-solar planet of about three Earth masses orbiting a star with a mass so low that its core may not be large enough to maintain nuclear reactions. The result was presented Monday (June 2) at the American Astronomical Society annual... view more... (2008-06-03)
Astronomers discover distant, icy Earth-like planet
An international team of astrophysicists has discovered a new planet five times the size of Earth, the smallest extrasolar planet revealed to date outside of our solar system. view more (2006-01-27)
Scientists find a solar-powered asteroid
An international research team led by Academy Research Fellow Mikko Kaasalainen has found an asteroid whose rotation receives an extra kick from solar radiation. view more (2007-03-08)
Planet or failed star? One of smallest stellar companions seen by Hubble
Astronomers using the NASA/ESA Hubble Space Telescope have photographed one of the smallest objects ever seen around a normal star beyond our Sun. Weighing in at 12 times the mass of Jupiter, the object is small enough to be a planet. view more (2006-09-11)
NASA spacecraft ready to explore outer solar system
The first NASA spacecraft to image and map the dynamic interactions taking place where the hot solar wind slams into the cold expanse of space is ready for launch Oct. 19. The two-year mission will begin from the Kwajalein Atoll, a part of the Marshall Islands in the Pacific Ocean. view more (2008-10-07)
Meteorites are rich in the building blocks of life, claims new research
Amino acids that are the building blocks of life have been found in their highest ever concentration in two ancient meteorites which crashed to Earth millions of years ago, scientists claim today. view more (2008-03-14)
NASA predicts nongreen plants on other planets
NASA scientists believe they have found a way to predict the color of plants on planets in other solar systems. view more (2007-04-11)
A Warm South Pole? Yes, on Neptune!
An international team of astronomers using ESO's Very Large Telescope has discovered that the south pole of Neptune is much hotter than the rest of the planet. This is consistent with the fact that it is late southern summer and this region has been in sunlight for about 40 years. view more (2007-09-19)
Hunt for planets outside solar system uncovers a small one
Perhaps edging closer to finding planets that harbor life, astronomers have discovered the smallest planet yet identified outside our solar system. view more (2006-01-26)
New laser technique may help find supernova
One single atom of a certain isotope of hafnium found on Earth would prove that a supernova once exploded near our solar system. view more (2009-08-12)
It's our solar system Jim, but not as we know it
There are many more objects orbiting our sun than we once thought, and a new book from Cambridge University Press sets out to tell the story of their discovery. Beyond Pluto: Exploring the Outer Limits of the Solar System by John Davies traces the history of the search for objects at the periphery of the solar system. It is a tale of incredible... view more... (2001-07-25)
Where did Venus's water go?
Venus Express has made the first detection of an atmospheric loss process on Venus's day-side. Last year, the spacecraft revealed that most of the lost atmosphere escapes from the night-side. view more (2008-12-19)
Astronomers discover two new planets, both among the hottest ever
Astronomers have discovered two new planets outside our solar system, both extremely close to their stars and thus among the hottest ever found. view more (2006-09-27)
Magnetic Tornadoes Could Liberate Mercury's Tenuous Atmosphere
As the closest planet to the sun, Mercury is scorching hot, with daytime temperatures of more than 800 degrees Fahrenheit (approximately 450 degrees Celsius). view more (2009-06-03)
Mars Express discovers aurorae on Mars
ESA's Mars Express spacecraft has for the first time ever detected an aurora on Mars. This aurora is of a type never previously observed in the Solar System. view more (2005-06-10)
Planet Orbiting a Giant Red Star Discovered with Hobby-Eberly Telescope
A planet orbiting a giant red star has been discovered by an astronomy team led by Penn State's Alex Wolszczan, who in 1992 discovered the first planets ever found outside our solar system. view more (2007-08-03)
New capture scenario explains origin of Neptune's oddball moon Triton
Neptune's large moon Triton may have abandoned an earlier partner to arrive in its unusual orbit around Neptune. view more (2006-05-11)
The IAU draft definition of 'planet' and 'plutons'
The world's astronomers, under the auspices of the International Astronomical Union (IAU), have concluded two years of work defining the difference between "planets" and the smaller "solar system bodies" such as comets and asteroids. view more (2006-08-16)
DOE outlines research needed to improve solar energy technologies
To help achieve the Bush Administration's goal of increased use of solar and other renewable forms of energy, the Department of Energy's (DOE) Office of Science has released a report describing the basic research needed to produce "revolutionary progress in bringing solar energy to its full potential in the energy marketplace." view more (2005-08-15)
