The Kepler space telescope is designed to look for planets like Earth that could have life. But no one expected it to find 54 planet-candidates at Goldilocks distances from their stars – not too warm or cold for life as we know it – in its first four months of operation.
A new Hubble Space Telescope image of a celestial object called the Ant Nebula may shed new light on the future demise of our Sun. The Ant Nebula, whose technical name is Mz3, resembles the head and thorax of an ant when observed with ground-based telescopes. The new Hubble image, with 10 times the resolution revealing 100 times more detail, shows the 'ant's' body as a pair of fiery lobes protruding from a dying, Sun-like star. The Ant Nebula is located between 3,000 and 6,000 light years from Earth in the southern constellation Norma.
Tropical storm Irene approaches Puerto Rico (l.) in this image taken from the MODIS instrument on NASA's Aqua satellite on August 21. Categorized as a hurricane, Irene buffeted Puerto Rico with winds and torrential rain August 22, knocking out power and downing trees as it churned westward to threaten Florida by the end of the week.
A burping black hole, water in weird places, and whopper-size new planets are some top space stories of 2010. If you have different discoveries on your list, post them in the comments section.
Cal Tech astronomer and author Mike Brown helped to demote Pluto from planethood – and got a lot of hate mail as a result.
Voyager 1: Since 2004, the Voyager 1 probe has been exploring a region of space where solar wind slows abruptly and crashes into the thin gas between stars.
The thin line of Earth's atmosphere and the setting sun are featured in this image photographed by the crew of the International Space Station while space shuttle Atlantis was docked with the station in 2009.
New calculations indicate that Pluto might be the largest object in the outer solar system. Does it now deserve to be called a planet again?
For the first time, scientists have found a solar system that was not formed in the Milky Way galaxy. What's more, the planet is in danger of being eaten by its host star.
