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.....»»
Jupiter"s moon Europa produces less oxygen than we thought—it may affect our chances of finding life there
Jupiter's icy moon Europa has long been thought of as one of the most habitable worlds in the Solar System. Now the Juno mission to Jupiter has directly sampled its atmosphere in detail for the first time. The results, published in Nature Astronomy,.....»»
NASA unveils design for message heading to Jupiter"s moon Europa
When it launches in October, the agency's Europa Clipper spacecraft will carry a richly layered dispatch that includes more than 2.6 million names submitted by the public......»»
Jet in Jupiter"s atmosphere found to fluctuate in roughly four-year periods
A team of planetary scientists affiliated with multiple institutions in the U.S. has found a jet in Jupiter's atmosphere that fluctuates in roughly four-year periods. In their paper published in the journal Nature, the group describes how they found.....»»
Jupiter’s icy moon Europa may be light on oxygen, lowering habitability hopes
New research pours cold water on the likelihood of Europa being habitable, as it seems that the moon produces less oxygen than previously thought......»»
Meltwater in the north Atlantic can lead to European summer heat waves, study finds
Scientists from the National Oceanography Centre (NOC) have discovered that increased meltwater in the North Atlantic can trigger a chain of events leading to hotter and drier European summers......»»
Lab study creates artificial magnetosphere to explore spontaneous excitation of chorus emissions
A dipole magnetic field, created by a ring current, is the most fundamental type of magnetic field that is found both in laboratories and in space. Planetary magnetospheres, such as Jupiter's, effectively confine plasma......»»
Spot the king of planets: Observe Jupiter
Jupiter is our solar system's undisputed king of the planets. Jupiter is bright and easy to spot from our vantage point on Earth, helped by its massive size and banded, reflective cloud tops. Jupiter even possesses moons the size of planets: Ganymede.....»»
Astronomers discover Jupiter-sized objects drawn into each other"s orbit
In our most basic understanding of our solar system, planets are drawn into the orbit of our massive star, the sun. But what happens to planet-sized objects that don't have a star? A team of astronomers studying Jupiter-mass binary objects (JuMBOs) i.....»»
Weather v climate: How to make sense of an unusual cold snap while the world is hotter than ever
Earlier this year, the UK's weather and climate service, the Met Office, announced average global temperatures in 2023 were 1.46°C above pre-industrial levels. This made it the hottest year on record, 0.17°C higher than the previous record in 2016......»»
Did the Galileo mission find life on Earth?
In the fall of 1989, the Galileo spacecraft was launched into space, bound for Jupiter and its family of moons. Given the great distance to the king of planets, Galileo had to take a roundabout tour through the inner solar system, making a flyby of V.....»»
World sees first 12 months above 1.5C warming level: climate monitor
Earth has endured 12 months of temperatures 1.5C hotter than the pre-industrial era for the first time on record, Europe's climate monitor said Thursday, in what scientists called a "warning to humanity"......»»
For your processing pleasure: The sharpest pictures of Jupiter"s volcanic moon Io in a generation
NASA's Juno spacecraft has just made the closest flybys of Jupiter's moon Io that any spacecraft has carried out in more than 20 years. An instrument on this spacecraft called "JunoCam" has returned spectacular, high-resolution images—and raw data.....»»
NASA"s Juno probe makes another close flyby of Io
The Juno spacecraft has revealed some fascinating things about Jupiter since it began exploring the system on July 4th, 2016. Not only is it the first robotic mission to study Jupiter up close while orbiting it since the Galileo spacecraft, which stu.....»»
The planet is dangerously close to this climate threshold: What 1.5°C really means
The alarm bells are loud and clear. Federal and international climate officials recently confirmed that 2023 was the planet's hottest year on record—and that 2024 may be even hotter......»»
NASA"s Lucy ready for 2024 mission milestones
After its successful first asteroid encounter in 2023, NASA's Lucy mission has its sights firmly set on its main targets, the never-before-explored Jupiter Trojan asteroids. In 2024, the Lucy spacecraft will transition from its current orbit around t.....»»
"It"s not game over—it"s game on": Why 2024 is an inflection point for the climate crisis
In 2024, global climate trends are cause for both deep alarm and cautious optimism. Last year was the hottest on record by a huge margin and this year will likely be hotter still. The annual global average temperature may, for the first time, exceed.....»»
TESS discovers nine new "hot Jupiters"
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered nine new "hot Jupiter" exoplanets. One of the newly detected alien worlds is almost four times more massive than Jupiter. The finding was p.....»»
The Surprising Things That Helped Make 2023 the Hottest Year Ever
The numbers are in: 2023’s global temperatures not only soared, but smashed the previous record set in 2016. This year could be even hotter......»»
Climate change spells disaster for termite-loving numbats
Australia is known for its wonderous and unique wildlife. But, just like the rest of the world, Australia is expected to get even hotter due to climate change. This could spell disaster for many of the marsupials that call the drier regions of the co.....»»
Scientists investigate how heat rises through Europa"s ocean
Europa, one of Jupiter's many moons, may be capable of supporting life because its icy surface likely obscures a deep, salty ocean. Europa's ocean is also in direct contact with its mantle rocks, and interactions between rock, water, and ice could pr.....»»
