TESS discovers an old warm Jupiter-like exoplanet
Using the Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has detected a new old and warm Jupiter-like alien world orbiting a G-dwarf star. The newfound exoplanet, designated TOI-5542 b, is the size of Jupiter—abo.....»»
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......»»
New study disputes Hunga Tonga volcano"s role in 2023–24 global warm-up
New research from a collaborative team featuring Texas A&M University atmospheric scientist Dr. Andrew Dessler is exploring the climate impact of the 2022 Hunga Tonga volcano eruption and challenging existing assumptions about its effects in the proc.....»»
Perseverance rover discovers rock with potential signs of ancient life
A vein-filled rock is catching the eye of the science team of NASA's Perseverance rover. Nicknamed "Cheyava Falls" by the team, the arrowhead-shaped rock contains fascinating traits that may bear on the question of whether Mars was home to microscopi.....»»
Webb directly images giant exoplanet that isn’t where it should be

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.....»»

Effects of stellar magnetism could expand criteria for exoplanet habitability
Interest in Earth-like planets orbiting within the habitable zone of their host stars has surged, driven by the quest to discover life beyond our solar system. But the habitability of such planets, known as exoplanets, is influenced by more than just.....»»
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:.....»»
Don"t underestimate the increasingly warm summer temperatures, says Swiss expert
What's happened to the summer? I've been asked this question a lot over the past few weeks. Just like May, June was changeable, wet and lacking in sunshine. But it wasn't too cold. According to MeteoSwiss, the average daily temperature in June was st.....»»
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.....»»
NASA"s Curiosity rover discovers a surprise in a Martian rock
Scientists were stunned on May 30 when a rock that NASA's Curiosity Mars rover drove over cracked open to reveal something never seen before on the Red Planet: yellow sulfur crystals......»»
One half of this wild exoplanet reaches temperatures of 1,450 degrees Fahrenheit

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......»»
Exoplanet-hunting telescope to begin search for another Earth in 2026
Europe's next big space mission—a telescope that will hunt for Earth-like rocky planets outside of our solar system—is on course to launch at the end of 2026......»»
Slower metabolism of warm-blooded animals on islands correlated with higher risk of anthropogenic extinction
A multi-institutional team of zoologists and animal behavioral specialists in China and Germany has found an association between the slower metabolism of island-dwelling, warm-blooded animals and an increased risk of anthropogenic extinction......»»
Discovery alert: With six new exoplanets, 5,500 discovery milestone passed
On Aug. 24, 2023, more than three decades after the first confirmation of planets beyond our own solar system, scientists announced the discovery of six new exoplanets, stretching that number to 5,502. From zero exoplanet confirmations to more than 5.....»»
Researchers predict fewer, pricier strawberries as temperatures warm
Strawberries could be fewer and more expensive because of higher temperatures caused by climate change, according to research from the University of Waterloo......»»
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.....»»
