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.....»»
New data on radiation show missions to Jupiter"s moon Europa are possible
Scientists from NASA's Juno mission have developed the first complete 3D radiation map of the Jupiter system, including characterizing the intensity of the high-energy particles near the orbit of the icy moon Europa, and how the radiation environment.....»»
Image: Juice snaps moon en route to Earth
During the first step of humankind's first-ever lunar-Earth flyby, ESA's Jupiter Icy Moons Explorer (Juice) mission captured this stunning view of the moon......»»
How to See the Conjunction Between Mars, Jupiter, and the Moon
On the 27th, the celestial bodies will form an unusual triangle in the sky just before dawn......»»
New massive eccentric brown dwarf discovered
An international team of astronomers has reported the discovery of a new brown dwarf, which received designation TOI-2490 b. The newfound object is about 74 times more massive than Jupiter and orbits a sun-like star on a highly eccentric orbit. The f.....»»
Mars and Jupiter get chummy in the night sky. The planets won"t get this close again until 2033
Mars and Jupiter are cozying up in the night sky for their closest rendezvous this decade......»»
Check out NASA’s top skywatching tips for August
NASA’s top skywatching tips for August include a meetup of Jupiter and Mars, a look at the Perseid meteors, and a view of the Lagoon Nebula......»»
Why the solar corona is so much hotter than sun"s surface
In a new study published in The Astrophysical Journal, a researcher from The University of Alabama in Huntsville (UAH), a part of the University of Alabama System, explores critical aspects of a phenomenon called kinetic Alfvén waves (KAWs) to provi.....»»
Discovery sheds light on the origins of matter in the early universe
The early universe was 250,000 times hotter than the core of our sun. That's far too hot to form the protons and neutrons that make up everyday matter. Scientists recreate the conditions of the early universe in particle accelerators by smashing atom.....»»
Spacecraft to swing by Earth, moon on path to Jupiter
A spacecraft launched last year will slingshot back around Earth and the moon next month in a high-stakes, world-first maneuver as it pinballs its way through the solar system to Jupiter......»»
Is this how you get hot Jupiters?
When we think of Jupiter-type planets, we usually picture massive cloud-covered worlds orbiting far from their stars. That distance keeps their volatile gases from vaporizing from stellar heat, similar to what we're familiar with in our solar system......»»
Webb directly images giant exoplanet that isn’t where it should be
Six times bigger than Jupiter, the planet is the oldest and coldest yet imaged. Enlarge / Image of Epsilon Indi A at two wavelengths, with the position of its host star indicated by an asterisk. (credit: T. Müller (MPIA/HdA), E......»»
James Webb takes rare direct image of a nearby super-Jupiter
The James Webb Space Telescope has directly imaged a gas giant beyond our solar system, and it's one of the coldest exoplanets observed so far......»»
Webb images nearest super-Jupiter, opening a new window to exoplanet research
Using the James Webb Space Telescope (JWST), an MPIA-led team of astronomers imaged a new exoplanet that orbits a star in the nearby triple system Epsilon Indi. The planet is a cold super-Jupiter exhibiting a temperature of around 0 degrees Celsius a.....»»
Introducing Ramses, ESA"s 2029 mission to asteroid Apophis
Thirty years ago, on 16 July 1994, astronomers watched in awe as the first of many pieces of the Shoemaker-Levy 9 comet slammed into Jupiter with incredible force. The event sparked intense interest in the field of planetary defense as people asked:.....»»
NASA sounding rocket launches, studies heating of sun"s active regions
Investigators at NASA's Marshall Space Flight Center in Huntsville, Alabama, will use observations from a recently-launched sounding rocket mission to provide a clearer image of how and why the sun's corona grows so much hotter than the visible surfa.....»»
Signatures of life could survive near surfaces of the moons Enceladus and Europa, NASA experiment suggests
Europa, a moon of Jupiter, and Enceladus, a moon of Saturn, have evidence of oceans beneath their ice crusts. A NASA experiment suggests that if these oceans support life, signatures of that life in the form of organic molecules (e.g. amino acids, nu.....»»
A new explanation for Jupiter"s shrinking Great Red Spot
Jupiter's Great Red Spot—the biggest windstorm in the solar system—is shrinking, and a new study may help explain why......»»
Astronomers spot a "highly eccentric" planet on its way to becoming a hot Jupiter
Hot Jupiters are some of the most extreme planets in the galaxy. These scorching worlds are as massive as Jupiter, and they swing wildly close to their star, whirling around in a few days compared to our own gas giant's leisurely 4,000-day orbit arou.....»»
Intel CPUs may get even hotter
New leaks about Intel Arrow Lake and Panther Lake suggest that these next-gen CPUs will have a higher maximum temperature......»»
Juice"s lunar-Earth flyby: All you need to know
ESA's Jupiter Icy Moons Explorer (Juice) will return to Earth on 19–20 August, with flight controllers guiding the spacecraft first past the moon and then past Earth itself. This "braking" maneuver will take Juice on a shortcut to Jupiter via Venus.....»»
