A "Jupiter" hotter than the sun
The search for exoplanets—planets that orbit stars located beyond the borders of our solar system—is a hot topic in astrophysics. Of the various types of exoplanets, one is hot in the literal sense: hot Jupiters, a class of exoplanets that are ph.....»»
In last 15 years, deforestation made outdoor work unsafe for millions
The tropics is becoming hotter due to a combination of warming associated with deforestation and climate change -- and that can reduce the ability of outdoor workers to perform their jobs safely. Researchers estimated how many safe working hours peop.....»»
2022 Will Be a Big Year for Space Exploration
Missions to Mars, Jupiter, and—yes—Texas are all part of the next wave of space research previously delayed by Covid-19......»»
NASA Releases New Photos of Jupiter - and a Recording of Its Moon that Sounds Like R2-D2
"As it seeks answers about the cosmos and what they mean for Earth's origins, NASA on Friday announced a slew of discoveries about Jupiter," reports the Washington Post "And scientists brought home an interstellar tune from the road." The Juno sp.....»»
Hear the sounds of Jupiter’s moon, Ganymede, as captured by the Juno spacecraft
The Juno spacecraft is famous for capturing images of Jupiter. But Juno scientists have released an audio track of its flyby of Jupiter's moon Ganymede......»»
Juno spacecraft "hears" Jupiter"s moon
Sounds from a Ganymede flyby, magnetic fields, and remarkable comparisons between Jupiter and Earth's oceans and atmospheres were discussed during a briefing today on NASA's Juno mission to Jupiter at the American Geophysical Union Fall Meeting in Ne.....»»
Four new giant exoplanets detected
An international team of astronomers reports the detection of four new giant alien worlds as part of the HATSouth photometric survey. The newfound exoplanets are the size of Jupiter and received designations HATS-74Ab, HATS-75b, HATS-76b and HATS-77b.....»»
Citizen scientists find young-Jupiter-like object missed by previous exoplanet searches
Citizen scientists have discovered a new object orbiting a Sun-like star that had been missed by previous searches. The object is very distant from its host star—more than 1,600 times farther than the Earth is from the Sun—and is thought to be a.....»»
Revealed: Jupiter’s Secret Power Source
For all its other problems, Earth is lucky. Warmed mostly by the sun, 150 million km away, shielded by a thin but protective atmosphere, the temperature at the surface averages 14 to 15 degrees Celsius—a good number to support liquid oceans and a.....»»
Astronomers discover ancient brown dwarf with lithium deposits intact
Brown dwarfs, also known as "coffee colored dwarfs" or "failed stars" are the natural link between stars and planets. They are more massive than Jupiter but now sufficiently to burn hydrogen, which is the fuel the stars use to shine. For that reason.....»»
Qualcomm Has an Exclusivity Deal With Microsoft For Windows On ARM
An anonymous reader quotes a report from XDA Developers: Last week, we reported that MediaTek is planning to build a chipset for Windows on ARM. As it turns out, the Windows on ARM chipset space could be even hotter than that, because there's a reaso.....»»
Go on a ‘Grand Tour’ of the outer solar system with these Hubble images
Each year Hubble snaps images of the outer planets of our solar system -- Jupiter, Saturn, Uranus, and Neptune -- to see how they are changing over time......»»
Check out Hubble"s annual tour of the outer solar system
Hubble’s tour, part the Outer Planets Atmospheres Legacy program, or OPAL, starts with Jupiter. This year’s image, captured on September 4, highlights the planet’s tumultuous atmosphere and reveals several new storms taking shape. The planet’.....»»
Hubble takes a grand tour of the solar system
The NASA/ESA Hubble Space Telescope has completed its annual grand tour of the outer Solar System. This is the realm of the giant planets—Jupiter, Saturn, Uranus, and Neptune—extending as far as 30 times the distance between Earth and the Sun. Un.....»»
Space Rocks Keep Hitting Jupiter. What"s the Deal with That?

Weird weather: Metal rain and super-high temperatures on an ultra-hot exoplanet
Ultra-hot Jupiters—named as such because of their physical similarities to the planet Jupiter—are exoplanets that orbit stars other than the sun with temperatures so high that the molecules in their atmospheres are completely torn apart. They are.....»»
Integrating hot cores and cool edges in fusion reactors
Future fusion reactors have a conundrum: maintain a plasma core that is hotter than the surface of the sun without melting the walls that contain the plasma. Fusion scientists refer to this challenge as "core-edge integration." Researchers working at.....»»
Climate Change Is Acidifying and Contaminating Drinking Water and Alpine Ecosystems
Hotter, drier mountains leach more metal into streams from abandoned mines and natural deposits -- Read more on ScientificAmerican.com.....»»
On ancient Earth, it never rained but it poured
Today, we are experiencing the dramatic impacts that even a small increase in global temperatures can have on a planet's climate. Now, imagine an Earth 20 to 30 degrees Fahrenheit (11 - 17 C) hotter than today. Earth likely experienced these temperat.....»»
Can selective breeding of "super kelp" save our cold water reefs from hotter seas?
Australia's vital kelp forests are disappearing in many areas as our waters warm and our climate changes......»»
