Unlike our solitary Sun, most stars form in binary pairs -- two stars that orbit a common center of mass. Though remarkably plentiful, binaries pose a number of questions, including how and where planets form in such complex environments. Stars... Continue reading

Earth and Mercury are both rocky planets with iron cores, but Mercury's interior differs from Earth's in a way that explains why the planet has such a bizarre magnetic field, UCLA planetary physicists and colleagues report. Measurements from NASA's Messenger... Continue reading

The Milky Way is smaller than astronomers previously thought, according to new research. For the first time, scientists have been able to precisely measure the mass of the galaxy that contains our solar system. Researchers have found that the Milky... Continue reading

Astronomers have long known that interstellar molecules containing carbon atoms exist and that by their nature they will absorb light shining on them from stars and other luminous bodies. Because of this, a number of scientists have previously proposed that... Continue reading

The Universe is a big place, full of unknowns. Astronomers using NASA's Chandra X-ray Observatory have just catalogued a new one."I couldn't believe my eyes," says Esra Bulbul of the Harvard Center for Astrophysics. "What we found, at first glance,... Continue reading

The difference between earth and the space station is buoyancy. When droplets of fuel burn on earth, buoyancy limits the amount of time gases can hang around in the high temperature zone around the droplets. So there isn’t enough time... Continue reading

The Bubble Nebula or NGC 7635 is 10 light-year diameter object a mere 11,000 light-years away toward the constellation Cassiopeia near a giant molecular cloud which contains the expansion of the bubble. Above and right of the Bubble's center is... Continue reading

In findings that help astrophysicists understand our corner of the galaxy, an international research team has shown that the soft X-ray glow blanketing the sky comes from both inside and outside the solar system. “We now know that the emission... Continue reading

The surface of Mars is incredibly violent, hostile and destructive to any kind of biosignature, whereas things get preserved much better when they are buried. Astrobiologits are thinking that if there’s life on Mars or if there’s evidence of past... Continue reading

Large clumps of mass in the Universe warp and distort the space-time around them. Acting like lenses, they appear to magnify and bend light that travels through them from more distant objects. This warping of space-time by large objects in... Continue reading

A team of astronomers using NASA's Hubble Space Telescope have gone looking for water vapour in the atmospheres of three planets orbiting stars similar to the Sun – and have come up nearly dry. The three planets, HD 189733b, HD... Continue reading

In 2012, the Voyager mission team announced that the Voyager 1 spacecraft had passed into interstellar space, traveling further from Earth than any other manmade object. But, in the nearly two years since that historic announcement, and despite subsequent observations... Continue reading

By using Chandra, astronomers can peer into the Whirlpool Galaxy to uncover things that can only be detected in X-rays. In this new composite image, Chandra data are shown in purple. Optical data from the Hubble Space Telescope are red,... Continue reading

In late June 2013, an exceptional binary containing a rapidly spinning neutron star underwent a dramatic change in behavior never before observed. The pulsar's radio beacon vanished, while at the same time the system brightened fivefold in gamma rays, the... Continue reading

A new home-grown instrument based on bundles of optical fibres is giving Australian astronomers the first 'Google street view' of the cosmos — incredibly detailed views of huge numbers of galaxies. Developed by researchers at the University of Sydney and... Continue reading
Image
The stars of the first generation were formed out of a primordial gas which consisted only of hydrogen and helium. Their mass ranged from ten to five hundred times the mass of our Sun. Nuclear processes in the interior of... Continue reading

By utilising the unique space-based location of the NASA/ESA Hubble Space Telescope and its sensitive Advanced Camera for Surveys and Wide Field Camera 3/, a team of astronomers has probed the halo surrounding the prominent giant elliptical galaxy Centaurus A,... Continue reading

Astronomers have discovered a transiting exoplanet with the longest known year. Kepler-421b circles its star once every 704 days. In comparison, Mars orbits our Sun once every 780 days. Most of the 1,800-plus exoplanets discovered to date are much closer... Continue reading

"Early in 2013 we announced our startling discovery that half of the dwarf galaxies surrounding the Andromeda Galaxy are orbiting it in an immense plane," said Geraint Lewis, of the University of Sydney's School of Physics. "This plane is more... Continue reading

An extraterrestrial spacecraft lurking in a satellite’s orbit near Earth would be able to see city lights and pollution in our atmosphere. But what if it searched for signs of life on Earth from afar? This question has great pertinence... Continue reading

Researchers have made an important step in the race to discover whether other planets could develop and sustain life. New findings published today in the journal Astrobiology shows the vital role of oceans in moderating climate on Earth-like planets. Until... Continue reading

Lawrence Livermore scientists for the first time have experimentally re-created the conditions that exist deep inside giant planets, such as Jupiter, Uranus and many of the planets recently discovered outside our solar system. The data described in this work are... Continue reading

Newly discovered soils by NASA's Curiosity rover provide more benign and habitable soil conditions than known before on Mars. Their dating to 3.7 billion years ago, he noted, puts them into a time of transition from "an early benign water... Continue reading

A collision of one universe with another would leave what Perimeter Institute's Matthew Johnson, calls “a disk on the sky” – a circular bruise in the cosmic microwave background. That the search for such a disk has so far come... Continue reading

Curiosity's ChemCam's laser has zapped more than 600 rock and soil targets on Mars since Curiosity landed in the planet's Gale Crater in August 2012 to assess ancient habitable environments and major changes in Martian environmental conditions. On Saturday, July... Continue reading
