The same kind of large-scale planetary waves that meander through the atmosphere high above Earth's surface may also exist on the Sun, according to a new study led by a scientist at the National Center for Atmospheric Research (NCAR). Just... Continue reading

"The possibility that a large ocean once occupied the Martian northern plains is one of the most important and controversial hypotheses to have originated from the exploration of Mars," the researchers wrote in the study. "We mapped lobate deposits, which... Continue reading

"This is a challenging experiment because we're having to look through a foreground — namely, the Milky Way galaxy — that is at least four orders of magnitude brighter than the signal that we're trying to detect," said Jack Burns,... Continue reading

An international team of astronomers has identified a record breaking brown dwarf (a star too small for nuclear fusion) with the 'purest' composition and the highest mass yet known. The object, known as SDSS J0104+1535, is a member of the... Continue reading

NASA's Juno spacecraft will make its fifth flyby over Jupiter's mysterious cloud tops on Monday, March 27, at 1:52 a.m. PDT (4:52 a.m. EDT, 8:52 UTC). At the time of closest approach (called perijove), Juno will be about 2,700 miles... Continue reading

Astronomers have uncovered a supermassive black hole that has been propelled out of the center of a distant galaxy by what could be the awesome power of gravitational waves. Though there have been several other suspected, similarly booted black holes... Continue reading

“We discovered the so far largest ordered magnetic fields in the universe, extending over 5-6 million light years”, says Maja Kierdorf from Max Planck Institute Bonn. Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at... Continue reading

Once upon a time, the Universe was just a hot soup of particles. In those days, together with visible particles, other particles to us hidden or dark might have formed. Billions of years later scientists cataloged 17 types of visible... Continue reading

The Rosetta spacecraft documented unique changes spotted on comet 67p/Churyumov-Gerasimenko as it approached the sun --growing fractures, collapsing cliffs and rolling boulders on the comet's surface. A study published March 21, 2017 in the journal Science summarizes the types of... Continue reading

Astronomers have developed a way to detect the ultraviolet (UV) background of the Universe, which could help explain why there are so few small galaxies in the cosmos. UV radiation is invisible but shows up as visible red light when... Continue reading

The silence of an immense desolate land in which to search for reverberations coming from the time at which everything began. The Simons Observatory will be built in the Chilean Atacama desert at an altitude of several thousand meters for... Continue reading

"We estimate that the peak activity for the volcanic field at the summit of Arsia Mons probably occurred approximately 150 million years ago--the late Jurassic period on Earth--and then died out around the same time as Earth's dinosaurs," said Jacob... Continue reading

A team of scientists has discovered that a law controlling the bizarre behavior of black holes out in space—is also true for cold helium atoms that can be studied in laboratories. "It's called an entanglement area law," says Adrian Del... Continue reading

It's possible that Mars had rings at one point and may have them again someday. That's the theory put forth by Purdue University scientists have developed a model that suggests that debris that was pushed into space from an asteroid... Continue reading

"It's a cosmic miracle," said Volker Bromm of The University of Texas at Austin, referring to the precise set of conditions present half a billion years after the Big Bang that allowed these behemoths to emerge. "It's the only time... Continue reading

Neil deGrasse Tyson explores the future of humanity with one of the men forging that future: billionaire entrepreneur Elon Musk, CEO of SpaceX and Tesla Motors. Join us as Neil and Elon talk about NASA funding, getting humans excited for... Continue reading

Johns Hopkins University scientist Kirby Runyon wants to make one thing clear: Regardless of what one prestigious scientific organization says to the contrary, Pluto is a planet. So, he says, is Europa, commonly known as a moon of Jupiter, and... Continue reading

In 2024, China's space station will become operational at the same time when the International Space Station (ISS) shown above will retire, according to its current plans on development. The ISS is the most well-known artificial science laboratory on a... Continue reading

New observations indicate that massive, star-forming galaxies during the peak epoch of galaxy formation, 10 billion years ago, were dominated by baryonic or 'normal' matter. This is in stark contrast to present-day galaxies, where the effects of mysterious dark matter... Continue reading

Einstein's theory of gravity may have to be rewritten, after researchers at the University of St Andrews found a gigantic ring of galaxies darting away from us much faster than predicted. This 10 million light year-wide ring made up of... Continue reading
Image
A massive protostar, deeply nestled in its dust-filled stellar nursery, recently roared to life, shining nearly 100 times brighter than before. This outburst, apparently triggered by an avalanche of star-forming gas crashing onto the surface of the star, supports the... Continue reading

In the center of a distant galaxy, almost 300 million light years from Earth, scientists have discovered a supermassive black hole that is "choking" on a sudden influx of stellar debris. In a paper published today in Astrophysical Journal Letters,... Continue reading

NASA's Cassini spacecraft has found that the composition of Titan's lakes and seas varies from place to place, with some reservoirs being richer in ethane than methane. "Our experiments showed that when methane-rich liquids mix with ethane-rich ones -- for... Continue reading

NASA says it could study distant exoplanets by using the sun as a giant gravity lens revealing (if it was Earth) islands, rivers, parks, Great Walls, freeways, cities, and so on. Imagine an alien spacecraft sitting at the gravitational focus... Continue reading

The Solar Dynamics Observatory (SDO) has now captured nearly seven years worth of ultra-high resolution solar footage. This time lapse shows that full run from two of SDO's instruments. The large orange sun is visible light captured by HMI. The... Continue reading
