Immigration rally in N.Y.C. to mark World Refugee Day
19 hours ago
Hundreds of New Yorkers from refugee, immigrant, religious and advocacy communities held a march in observance of World Refugee Day. Marchers laid out 85 pairs of shoes to represent 85,000 refugees who were not allowed into the U.S. in 2018, carried orange rafts symbolizing refugee ocean crossings and read the names of refugees who died in transit.

Einstein Proven Right Even In Other Galaxies
23 hours ago
Albert Einstein’s name is synonymous with intelligence, but he’s more than earned his rep. The man revolutionized physics when he was in his 20s and 30s. He came up with a whole new way of understanding reality, not as a fixed grid against which events occur, but as fundamentally intertwined with time and perception. Trying to prove Einstein wrong, somehow, is a perennial goal of budding and experienced physicists alike. Well, they’ll have to keep trying. A new study in Scienc

Astronomers Catch a Black Hole Devouring Star
6/14/2018
Astronomers Seppo Mattila and Miguel Pérez-Torres usually study the natural deaths of stars, but they weren’t going to pass up the chance to investigate a stellar murder. A new paper in Science describes how they nabbed photographic evidence that a supermassive black hole in a relatively nearby galaxy tore apart and consumed part of a star in a phenomenon called a tidal disruption event (TDE), spewing jets of material in the process. Scientists have observed these cosmic crime scen

Astronomers observe star reborn in a flash
9/14/2016
An international team of astronomers using Hubble have been able to study stellar evolution in real time. Over a period of 30 years dramatic increases in the temperature of the star SAO 244567 have been observed. Now the star is cooling again, having been reborn into an earlier phase of stellar evolution. This makes it the first reborn star to have been observed during both the heating and cooling stages of rebirth. read more

NASA's THEMIS sees Auroras move to the rhythm of Earth's magnetic field
9/13/2016
The majestic auroras have captivated humans for thousands of years, but their nature -- the fact that the lights are electromagnetic and respond to solar activity -- was only realized in the last 150 years. Thanks to coordinated multi-satellite observations and a worldwide network of magnetic sensors and cameras, close study of auroras has become possible over recent decades. Yet, auroras continue to mystify, dancing far above the ground to some, thus far, undetected rhythm. read more

Discovery nearly doubles known quasars from the ancient universe
9/12/2016
Quasars are supermassive black holes that sit at the center of enormous galaxies, accreting matter. They shine so brightly that they are often referred to as beacons and are among the most-distant objects in the universe that we can currently study. New work from a team led by Carnegie's Eduardo Bañados has discovered 63 new quasars from when the universe was only a billion years old. (It's about 14 billion years old today.) read more

Astronomers discover rare fossil relic of early Milky Way
9/8/2016
Terzan 5, 19 000 light-years from Earth in the constellation of Sagittarius (the Archer) and in the direction of the galactic centre, has been classified as a globular cluster for the forty-odd years since its detection. Now, an Italian-led team of astronomers have discovered that Terzan 5 is like no other globular cluster known. read more

Reconciling dwarf galaxies with dark matter
9/7/2016
Dwarf galaxies are enigmas wrapped in riddles. Although they are the smallest galaxies, they represent some of the biggest mysteries about our universe. While many dwarf galaxies surround our own Milky Way, there seem to be far too few of them compared with standard cosmological models, which raises a lot of questions about the nature of dark matter and its role in galaxy formation. read more

NASA science flights study effect of summer melt on Greenland ice sheet
9/7/2016
Operation IceBridge, NASA's airborne survey of polar ice, is flying in Greenland for the second time this year, to observe the impact of the summer melt season on the ice sheet. The IceBridge flights, which began on August 27 and will continue until September 16, are mostly repeats of lines that the team flew in early May, so that scientists can observe changes in ice elevation between the spring and late summer. read more

Another Moon on Pluto Has Astronomers Aglow
7/13/2012
Pluto is still not a planet, but it does boast an impressive entourage. Astronomers said Wednesday that they had spotted a fifth moon orbiting Pluto, which they already knew had four. The discovery, made with the Hubble Space Telescope, gives Pluto more moons than Mercury, Venus, Earth and Mars combined.

Einstein proved right in another galaxy
Astronomers have made the most precise test of gravity outside our own solar system. By combining data taken with NASA's Hubble Space Telescope and the European Southern Observatory's Very Large Telescope, the researchers show that gravity in this galaxy behaves as predicted by Albert Einstein's general theory of relativity, confirming the theory's validity on galactic scales.

'Red nuggets' are galactic gold for astronomers
About a decade ago, astronomers discovered a population of small, but massive galaxies called "red nuggets." A new study using NASA's Chandra X-ray Observatory indicates that black holes have squelched star formation in these galaxies and may have used some of the untapped stellar fuel to grow to unusually massive proportions.
