Thanks to a phenomenon known as gravitational lensing, astronomers have spotted what might be the most distant object known to science, a distant galaxy cluster called IRC 0218.
The discovery of a colossal gas giant some 130 light-years from Earth could help explain the origins of our own solar system, say scientists.
Scientists have found 13 dwarf galaxies orbiting the Andromeda galaxy in what appears to be a fairly narrow ring. That makes no sense according to current models of galaxy formation.
A Christian Science perspective.
The discovery offers scientists a unique chance within the decade to test Einstein's theory of relativity in an extreme environment.
Using data from the Hubble telescope, scientists have found the oldest spiral galaxy in the universe, a galaxy that, according to current models, isn't supposed to exist.
The discovery with Hubble Space Telescope of a spiral galaxy, long before other galaxies are known to have formed, surprised scientists
A planet recently discovered orbiting a nearby star is located in the star's 'habitable zone,' meaning that it could support life as we know it.
Though telescopes can't spot the dwarf galaxy, scientists detected its presence through the tiny distortions its gravity causes to light that passes it by.
A team of astronomers reports that it has detected the most distant dwarf galaxy yet discovered orbiting an enormous elliptical galaxy some 10 billion light-years away.
