Astronomers Just Revealed One of The Most Extreme Planets Ever Discovered

Astronomers have taken detailed observations of an incredibly extreme exoplanet, detecting brutal surface temperatures in the region of 3,200 degrees Celsius (5,792 degrees Fahrenheit).

Those temperatures – measured by the European Space Agency's CHaracterising ExOPlanet Satellite (or CHEOPS) – are enough to melt all rocks and metals, and even turn them into a gaseous form.

While the exoplanet, named WASP-189b , is not quite as hot as the surface of our Sun (6,000 degrees Celsius or 10,832 degrees Fahrenheit), it's basically as toasty as some small dwarf stars.

Largest Extraterrestrial Diamonds Ever Discovered: Cosmic Diamonds Formed During Gigantic

Geoscientists from Goethe University have found the largest extraterrestrial diamonds ever discovered – a few tenths of a millimeter in size nevertheless – inside meteorites. Together with an international team of researchers, they have now been able to prove that these diamonds formed in the early period of our solar system when minor planets collided together or with large asteroids.

It is estimated that over 10 million asteroids are circling the Earth in the asteroid belt. They are relics from the early days of our solar system, when our planets formed out of a large cloud of gas and dust rotating around the sun. When asteroids are cast out of orbit, they sometimes plummet towards Earth as meteoroids. If they are big enough, they do not burn up completely when entering the atmosphere and can be found as meteorites.

X-ray data reveal 1st-ever planet orbiting stars in another galaxy | Space | EarthSky

While extragalactic “rogue” planets – not orbiting any star – have been reported before, the new exoplanet is the first to be detected orbiting stars in another galaxy. And not just any galaxy … but M51, the beautiful Whirlpool, 23 million light-years away.

The Whirlpool Galaxy (M51), where the candidate exoplanet M51-ULS-1b was detected by the Chandra X-ray Observatory. We see this galaxy face-on. Image via NASA / ESA/ S. Beckwith (STScI)/ the Hubble Heritage Team (STScI/AURA).

Planet collision simulations give clues to atmospheric loss from moon's origin

Researchers ran more than 300 supercomputer simulations to study the consequences that different huge collisions have on rocky planets with thin atmospheres.

Their findings have led to the development of a new way to predict the atmospheric loss from any collision across a wide range of rocky planet impacts that could be used by scientists who are investigating the Moon's origins or other giant impacts.

They also found that slow giant impacts between young planets and massive objects could add significant atmosphere to a planet if the impactor also has a lot of atmosphere.

Big find! Scientists spot giant alien planet orbiting close to dead star's corpse | Space

Astronomers have spotted signs of an intact giant planet circling a superdense stellar corpse known as a white dwarf , a new study reports.

The white dwarf in question, called WD 1856, is part of a three-star system that lies about 80 light-years from Earth. The newly detected, Jupiter-size exoplanet candidate, WD 1856 b, is about seven times larger than the white dwarf and zips around it once every 34 hours.

"WD 1856 b somehow got very close to its white dwarf and managed to stay in one piece," study lead author Andrew Vanderburg, an assistant professor of astronomy at the University of Wisconsin-Madison, said in a statement .

The Case of the Disappearing Planet – Now. Powered by Northrop Grumman

A planet is nearly disappearing before our eyes. Its atmosphere is so hot from its nearby sun that it is gradually being blown off into the depths of space.

And the evaporating exoplanet, which NASA identified as GJ 3470b, is not alone in facing a catastrophic future. Another slowly disappearing planet, GJ 436b, is also losing its atmosphere to space, though at a more gradual rate.

Two planets have already disappeared: The University of California at Santa Cruz reported that a double star system called BD +20 307, located some 300 light-years from Earth, contains large quantities of heated dust — the likely result of a recent collision of exoplanets.

Mixing of the planet's ocean waters is decreasing, and that is speeding up global warming, study

The layers of the world's oceans aren't mixing like they used to due to climate change, potentially speeding up how fast the planet will warm in the coming decades. This new finding, contained in a study published Monday in the journal Nature Climate Change, finds that the reduction in the mixing of ocean layers is piling up warm water near the surface while cutting back on the circulation of cold, deep water.

"I had to increase that to three classes a week, because there was so much demand for new students. And my personal practice -- I've been booking consistently a month in advance because I'm fully booked."

Chin, who also owns a crystals store, says some items have been consistently sold out. And that's never happened before.
