Ironing out the interiors of exoplanets
The discovery of more than 4,500 extra-solar planets has created a need for modelling their interior structure and dynamics. As it turns out, iron plays a key role......»»
Old stars don"t have hot Jupiters, suggests study
As we began to discover hundreds, then thousands of exoplanets, we found that there were two types of worlds unlike anything in our solar system. The first are super-Earths. These worlds straddle the line between large rocky worlds like Earth and sma.....»»
A new planet-hunting instrument has been installed on the Very Large Telescope
Exoplanet studies have come a long way in a short time. To date, 5,523 exoplanets have been confirmed in 4,117 systems, with another 9,867 candidates awaiting confirmation. With all these planets available for study, exoplanet researchers have been s.....»»
What Will Plants Be Like on Alien Worlds?
Scientists know enough about exoplanets to speculate about how simple plants might arise on them. But don't count on them being green......»»
Study sheds new light on strange lava worlds
Lava worlds, massive exoplanets home to sparkling skies and roiling volcanic seas called magma oceans, are distinctly unlike the planets in our solar system......»»
2025 Minis feature new EV powertrains and wild interiors
Mini's going almost all-in on electrification. Enlarge / It's recognizably a mini, but with a bold, modern look. (credit: Mini) BMW provided flights from Albany to Munich and back, and three nights in a hotel so we could.....»»
Scientists detect and validate the longest-period exoplanets found with TESS
Scientists from The University of New Mexico (UNM), and Massachusetts Institute of Technology (MIT) have detected and validated two of the longest-period exoplanets found by TESS to date. These long period large exoplanets orbit a K dwarf star and be.....»»
Non-gas giant has 73 times Earth’s mass, bewildering its discoverers
Neptune-sized planet has a density similar to pure silver. Enlarge (credit: NASA/JPL-Caltech) Scientists have been working on models of planet formation since before we knew exoplanets existed. Originally guided by the p.....»»
TESS has found thousands of possible exoplanets: Which ones should JWST study?
There are more than 5,000 confirmed exoplanets in our galaxy. That number is going to rise significantly in the next decade. The Transiting Exoplanet Survey Satellite (TESS) has already cataloged more than 4,000 candidate exoplanets, and the PLAnetar.....»»
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.....»»
Chinese scientists complete a concept study for a 6-meter space telescope to find habitable exoplanets
We have discovered more than 5,400 planets in the universe. These worlds range from hot jovians that closely orbit their star to warm ocean worlds to cold gas giants. While we know they are there, we don't know much about them. Characteristics such a.....»»
Using cosmic weather to study which worlds could support life
As the next generation of giant, high-powered observatories begin to come online, a new study suggests that their instruments may offer scientists an unparalleled opportunity to discern what weather may be like on far-away exoplanets......»»
Two additional exoplanets detected in a nearby planetary system
By conducting radial velocity (RV) follow-up observations of the GJ 367 planetary system with the High Accuracy Radial velocity Planet Searcher (HARPS), an international team of astronomers has detected two additional alien worlds, at least four time.....»»
Ultracold Gases Can Probe Neutron Star Guts
Earth-based analogs are opening new frontiers in studies of the superdense interiors of neutron stars.....»»
Greenhouse gas supplement increases warming and alters circulation patterns on Earth and Earth-like exoplanets
With the launch of the James Webb Space Telescope (JWST), the study of exoplanetary atmospheres and their potential habitability reached new heights. A team of researchers led by Dr. Assaf Hochman from the Institute of Earth Sciences at Hebrew Univer.....»»
An Astrobiologist’s Search for Life in Space—and Meaning on Earth
In Life on Other Planets, Aomawa Shields talks about her hunt for habitable exoplanets as a classically trained actress and one of the few Black women in astronomy......»»
Study increases probability of finding water on other worlds by 100-fold
A new analysis shows that there are probably many more Earth-like exoplanets with liquid water than had been thought, significantly increasing the chance of finding life. The work finds that even where the conditions are not ideal for liquid water to.....»»
Two new sub-Neptunes orbiting nearby stars discovered with TESS
An international team of astronomers reports the discovery of two new sub-Neptune exoplanets using NASA's Transiting Exoplanet Survey Satellite (TESS). The newfound alien worlds, designated TOI-2084 b and TOI-4184 b, orbit nearby M-dwarf stars and ar.....»»
Astronomers puzzled by "planet that shouldn"t exist"
The search for planets outside our solar system—exoplanets—is one of the most rapidly growing fields in astronomy. Over the past few decades, more than 5,000 exoplanets have been detected and astronomers now estimate that on average there is at l.....»»
Watching the watchers with Nancy Grace Roman
Astronomers are getting better at gathering data about exoplanets. We have discovered thousands of them, measuring their mass, size, and orbital parameters, and we are starting to measure other aspects such as their temperature and atmospheric compos.....»»
