Gas Spirals as Nurseries of Twin Stars

Stars form in interstellar clouds of molecular gas and dust.

For the first time, an international team of astronomers, led by Dr. James Geach from the University of Hertfordshire, has revealed the dramatic 'blow out' phase of galactic evolution.

At a recent meeting ESO's main governing body, the Council, gave the green light for the construction of the European Extremely Large Telescope (E-ELT) in two phases.

Pulsars are very dense neutron stars that are the size of a city (their radius approaches ten kilometers), which, like lighthouses for the universe, emit gamma radiation beams or X-rays when they rotate up to hundreds of times per second.

Using the world's largest radio telescope, two astronomers from Swinburne University of Technology in Australia have detected the faint signal emitted by atomic hydrogen gas in galaxies three billion light years from Earth, breaking the previous record distance by 500 million light years. Their results appear in a paper published in the journal Monthly Notices of the Royal Astronomical Society.

Strange Galaxy Perplexes Astronomers

With the help of citizen scientists, a team of astronomers has found an important new example of a very rare type of galaxy that may yield valuable insight on how galaxies developed in the early universe. The new discovery technique promises to give astronomers many more examples of this important and mysterious type of galaxy.

Youthful Compact Galaxies

Researchers using NASA's Hubble Space Telescope and Chandra X-ray Observatory have uncovered young, massive, compact galaxies whose raucous star-making parties are ending early.

The new Paramount film "Interstellar" imagines a future where astronauts must find a new planet suitable for human life after climate change destroys the Earth's ability to sustain us.

Hubble View of Bubbly Nebula

This image from Hubble's Wide Field Planetary Camera 2 showcases NGC 1501, a complex planetary nebula located in the large but faint constellation of Camelopardalis (The Giraffe).

By looking at the dark spaces between visible galaxies and stars the NASA/JPL CIBER sounding rocket experiment has produced data that could redefine what constitutes a galaxy.

When Did Galaxies Settle Down?

Astronomers have long sought to understand exactly how the universe evolved from its earliest history to the cosmos we see around us in the present day.

An international team of astronomers under the guidance of graduate student Leah Morabito of Leiden Observatory has for the first time discovered the largest carbon atoms outside our Milky Way with the LOFAR radio telescope.

Big Black Holes Can Block New Stars

Massive black holes spewing out radio-frequency-emitting particles at near-light speed can block formation of new stars in aging galaxies, a study has found.

Peering through a giant cosmic magnifying glass, NASA's Hubble Space Telescope has spotted a tiny, faint galaxy -- one of the farthest galaxies ever seen. The diminutive object is estimated to be more than 13 billion light-years away.

Space scientists at the University of Leicester have detected a curious signal in the X-ray sky -- one that provides a tantalizing insight into the nature of mysterious 'dark matter.'

A group of researchers led by Melina Bersten of Kavli IPMU recently presented a model that provides the first characterization of the progenitor for a hydrogen-deficient supernova.

Galaxy clusters are the largest objects in the Universe held together by gravity but their formation is not well understood.

Astronomers have found a pulsating, dead star beaming with the energy of about 10 million suns. This is the brightest pulsar - a dense stellar remnant left over from a supernova explosion - ever recorded.

The Milky Way As Seen From Orbit

This eye-catching panorama of the night sky and the Milky Way on Sept. 27. by One of the Expedition 41 crew members aboard the International Space Station.

Certain primordial stars--those between 55,000 and 56,000 times the mass of our Sun, or solar masses--may have died unusually. In death, these objects--among the Universe's first-generation of stars--would have exploded as supernovae and burned completely, leaving no remnant black hole behind.
