An astronomer has recreated the "Pillars of Creation," which the Hubble Space Telescope captured in a famous photo, using a computer simulation.
26 June 2014, 11:41 AM ET
A computer simulation shows how an interstellar cloud of gas and dust can collapse and expand over 1.6 million years, forming "elephant trunks" like the ones seen in the "Pillars of Creation." FULL STORY: http://goo.gl/4Ke1Sj

Astronomers have discovered an exoplanet in the star Gliese 832's "habitable zone" — the just-right range of distances that could allow liquid water to exist on a world's surface. The planet, known as Gliese 832c, lies just 16 light-years from Earth.

Scientists have just discovered a distant galaxy with a trio of supermassive black holes at its core. The new finding suggests tight-knit groups of these giant black holes are far more common than previously thought.

Earth's nearest star has bad weather too. The sun's bad weather, however, is more than just a little rain and lightning. Huge droplets of hot plasma about the size of Maine fall from the sun's outer atmosphere (the corona) down toward its surface.

NASA's Chandra X-ray Observatory and the European Space Agency's XMM-Newton satellite spotted a spike of X-ray emission coming from more than 70 galaxy clusters. The X-rays could be generated by the decay of one type of dark-matter particle.
24 June 2014, 03:06 PM ET
The mysterious signal was detected by NASA's X-Ray Observatory and ESA's XMM-Newton in the Perseus galaxy cluster and 73 others. Scientists think that this may be the work of a hypothetical particle called a sterile neutrino.
