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.....»»
Global heating may breach 1.5°C in 2024—here"s what that could look like
It's official: 2023 was Earth's hottest year ever recorded, beating the previous record set in 2016 by a huge margin. Last year was also the first in which the world was close to 1.5°C (1.48°C) hotter than the pre-industrial average (1850-1900). We.....»»
Jupiter has at least three magnetosheath jets, finds Voyager 2 data study
A team of astrophysicists and astronomers from Harbin Institute of Technology, Johns Hopkins University and Peking University has found evidence from Voyager 2 data showing that Jupiter has at least three magnetosheath jets. The study is published in.....»»
Ocean temperatures helped make 2023 the hottest year ever recorded
A multi-national team of scientists (China, U.S., New Zealand, Italy, and France) analyzes the temperature of the Earth annually. These scientists have found a fever that increases every year: For the past decade, each year has been hotter than the p.....»»
Webb finds signs of possible aurorae on isolated brown dwarf
Astronomers using NASA's James Webb Space Telescope have found a brown dwarf (an object more massive than Jupiter but smaller than a star) with infrared emission from methane, likely due to energy in its upper atmosphere. This is an unexpected discov.....»»
Centaurs gain comet-like characteristics through close encounters with Jupiter, Saturn
A rapid reshaping of orbits resulting from a close encounter with Jupiter or Saturn can lead Centaurs to exhibit comet-like activity, according to a Planetary Science Institute Senior Scientist Eva Lilly paper......»»
A Jupiter-sized planet has been hiding a big secret: A 350,000-mile-long tail
WASP-69b is having a hot girl summer that never ends. The huge gaseous exoplanet, roughly the size of Jupiter and approximately 160 light years from Earth, orbits its searing host star so closely that its atmosphere is boiling away at a rate of 200,0.....»»

Astrophysicists publish Kepler Giant Planet Search, an aid to "figure out where to find life"
A team of astrophysicists led by Lauren Weiss, assistant professor in the Department of Physics and Astronomy at the University of Notre Dame, created the first-ever catalog of small, Earth-like planets with Jupiter-like siblings (planets that share.....»»
Hotter weather caused by climate change could mean more mosquitos, according to study
A warmer environment could mean more mosquitos as it becomes harder for their predators to control the population, according to a recent study led by Virginia Commonwealth University researchers......»»
In hotter regions, mammals shown to seek forests and avoid human habitats
The cool of the forest is a welcome escape on a hot day. This is especially true for mammals in North America's hottest regions, according to a study from the University of California, Davis. The study indicates that, as the climate warms, preserving.....»»
We"re in an El Niño. So why has Australia been so wet?
After three La Niña summers many of us would have been expecting much hotter and drier conditions this spring and summer after the arrival of El Niño. Instead, in many parts of eastern Australia it's rained and rained over the last few weeks......»»
Could life exist in molecular clouds?
Our search for life beyond Earth is still in its infancy. We're focused on Mars and, to a lesser extent, ocean moons like Jupiter's Europa and Saturn's Enceladus. Should we extend our search to cover more unlikely places like molecular clouds?.....»»
Juice spacecraft gears up for first ever Earth-moon gravity boost
The Juice mission is on its way to Jupiter, and it will be carrying out the first gravity assist around both Earth and the moon......»»
Astronomers discover two "hot Jupiters" orbiting red-giant stars
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered two new "hot Jupiter" exoplanets. The newfound alien worlds, designated TOI-4377 b and TOI-4551 b, both orbit distant red-giant stars. The.....»»
