Scientists scanning the skies have located a small exoplanet with Earth-like characteristics except for one detail: it's scorching hot.
It's so cold that it's colder than the darkest voids of space, and scientists studying the Boomerang Nebula have now discovered that the nebula's ghostlike shape is not what it once seemed.
It's a galaxy far, far away. Astronomers scanning the heavens discovered the most distant known galaxy lying so far away that it gives scientists a look at the universe's infancy.
A massive asteroid made an unsettlingly close approach toward Earth this month and although it sailed by and left our planet unscathed, there's a small chance of a collision the next time it approaches, approximately 19 years from now.
Scientists using data from NASA's Hubble Space Telescope and the Keck Telescope in Hawaii have stumbled upon evidence of water in the remnants of an extrasolar body orbiting a white dwarf star, marking the first time water has been discovered on a rocky body.
Have you ever wondered how stars are born? And no, we're not talking about celebrity stars here but those twinkling celestial bodies you look up to every night.
Astronomers at Columbia's Universidad de Antioquia have discovered what have since been dubbed "Lazarus" comets, along with their origin: the comet graveyard. The team's findings may explain why some activity of comet-like objects has been spotted in the solar system.
Scientists using the Atacama Large Millimeter/submillimeter Array (ALMA) of radio telescopes have spotted the first snow line in a distant, infant solar system for the first. The findings reveal more about solar systems in general, and how frozen molecules could speed up the formation of planets.
Deep in a dark cloud, some 10,000 light-years away, a monster so large it will be the biggest of its kind in the Milky Way is being born, and it's teaching scientists a thing or two about how stars form.
Be sure to look up into the sky this weekend, because a once-a-year phenomenon dubbed the "Supermoon" will be lighting up the sky as the Sun goes down this Saturday night into Sunday morning. And judging from the 15 images we have of previous years' Supermoons, it's an event you won't want to miss.
Neutron stars, cosmic objects so dense they are only surpassed by black holes, have been known to suddenly increase their rotations in what astronomers dub a "glitch" due to superfluids within the star. In a rare reversal, scientists have a observed a special highly-magnetized neutron star - known as a magnetar - hitting the brakes
For years, scientists have been unsure why Venus developed to host vast swaths of molten rock, while the Earth cultivated countless species. Now, a group of Japanese scientists have discovered the key factor in each planet's contradictory development: distance from the sun.
The Ring Nebula, it seems, is not actually a true ring. Thanks to the keen eyes of the Hubble Space Telescope, astronomers have found that there is far more to this eye-dazzling cosmic phenomenon than initially believed.
According to a calculation by two noted biologists, life on Earth may not have come from Earth at all.
A new discovery has been made that once again proves Einstein really knew what he was talking about. Under extreme conditions, many scientists used to believe that the concept of General Relativity might not be accurate.
