“Our discovery, if confirmed, would explain how these monster black holes were born,” said Fabio Pacucci, lead author of the study, of Scuola Normale Superiore in Pisa, Italy. "This new result helps to explain why we see supermassive black holes... Continue reading

"These studies are providing increasingly sensitive results, slowly shrinking the box of parameters where dark matter particles can hide," said Alexander Kashlinsky, an astrophysicist at NASA Goddard. "The failure to find them has led to renewed interest in studying how... Continue reading

"The universe is probably filled with habitable planets, so many scientists think it should be teeming with aliens," said Aditya Chopra at Australia National University. "Early life is fragile, so we believe it rarely evolves quickly enough to survive. Most... Continue reading

“We found there are multiple atmospheric compositions that allow it to be warm enough to have surface liquid water,” said Aomawa Shields, the study’s lead author and a National Science Foundation astronomy and astrophysics postdoctoral fellow in UCLA’s department of... Continue reading

Bright spots on the dwarf planet Ceres continue to stump researchers, led by Paolo Molaro of the Trieste Astronomical Observatory in Italy, who conducted the observations using the HARPS spectrograph at ESO’s La Silla Observatory in Chile. Molaro's team made... Continue reading

Radar measurements of Mars' polar ice caps reveal that the mostly dry, dusty planet is emerging from an ice age, following multiple rounds of climate change. Understanding the Martian climate will help determine when the planet was habitable in the... Continue reading

"For decades, conventional wisdom held that large Jupiter-mass planets take a minimum of 10 million years to form," said Christopher Johns-Krull, the lead author of a new study about the planet, CI Tau b, that will be published in the... Continue reading

In principle, nothing that enters a black hole can leave the black hole. This has considerably complicated the study of these mysterious bodies on which generations of physicists have debated ever since 1916, the year their existence was hypothesized as... Continue reading

Scientists have been trying to puzzle out for decades why the universe seems to weigh more than it should, and so far the answer points to dark matter—an invisible substance that they still don’t clearly understand and is thought to... Continue reading

"It was previously assumed that planets with masses similar to Earth would be habitable simply because they were in the 'habitable zone,' said James Owen, Hubble Fellow and lead author of a new study from the Institute for Advanced Studies... Continue reading

An international team of scientists has identified a common phenomenon in galaxies that could explain why huge numbers of them turn into cosmic graveyards. Galaxies begin their existence as lively and colorful spiral galaxies, full of gas and dust, and... Continue reading

“Back then, Earth received only about 70 percent of the energy from the sun than it does today,” said Vladimir Airapetian, a solar scientist at NASA’s Goddard Space Flight Center. “That means Earth should have been an icy ball. Instead,... Continue reading

Hubble's successor, the James Webb Space Telescope (JWST), "represents the hopes and ambitions of the 10,000 astronomers who have already used the Hubble," said John Mather, Nobel laureate, astrophysicist at NASA's Goddard Space Flight Center, and the senior project scientist... Continue reading

Dark matter is a mysterious substance composing most of the material universe, now widely thought to be some form of massive exotic particle. An intriguing alternative view is that dark matter is made of black holes formed during the first... Continue reading

“The ability to measure the top quark mass precisely is fortuitous because it, together with the Higgs boson mass, tells us whether the universe is stable or not,” said Robert Kehoe, a physicist at Southern Methodist University. “That has emerged... Continue reading

The fate of water on Mars has been energetically debated by scientists because the planet is currently dry and cold, in contrast to the widespread fluvial features that etch much of its surface. Scientists believe that if water did once... Continue reading

An international team of scientists, including two professors and three graduate students from UCLA, has detected and confirmed the faintest early-universe galaxy ever, behind a galaxy cluster known as MACS2129.4-0741, which could help explain how 'cosmic dark ages' ended. Using... Continue reading

Galaxies, in all their forms from spirals to ellipticals from giants to dwarfs have been widely studied over the past Century. To the surprise of the scientific community last year a new type of galaxy was discovered, residing in a... Continue reading

“So far the Standard Model seems to explain matter, but we know there has to be something beyond the Standard Model,” said Denise Caldwell, director of the Physics Division of the National Science Foundation. “This potential new physics can only... Continue reading

"If you have a wormhole, then you can turn them into time machines for going backward in time," says Caltech's Kip Thorne. "Wormholes" are cosmic tunnels that can connect two distant regions of the universe, or even to a parallel... Continue reading

“The giant black holes in the cores of galaxies, a million to 20 billion times heavier than the Sun, therefore, cannot have been born in the death of a star. They must have formed in some other way, perhaps by... Continue reading
