This exoplanet has two suns – just like Tatooine
A team of astronomers has detected a Tatooine-like exoplanet which orbits two stars. A person living on the planet would see two suns in the sky......»»
Peculiar nova eruption inspected by astronomers
An international team of astronomers has employed NASA's Transiting Exoplanet Survey Satellite (TESS) to observe the eruption of Nova Vulpeculae 2021. Results of the observational campaign, published November 8 on the pre-print server arXiv, provide.....»»
This is a first: An exoplanet in a polar circumbinary disk surrounding two stars
We live in an age of exoplanet discovery. One thing we've learned is not to be surprised by the kinds of exoplanets we keep discovering. We've discovered planets where it might rain glass or even iron, planets that are the rocky core remnants of gas.....»»
TESS finds eight more super-Earths
NASA's Kepler spacecraft has discovered most of the confirmed exoplanets that we know of. But its successor, TESS (Transiting Exoplanet Survey Satellite), is catching up. New research announces the validation of eight more TESS candidates, and they'r.....»»
TESS discovers Saturn-like planet orbiting an M-dwarf star
Astronomers have discovered a new giant exoplanet orbiting an M-dwarf star using NASA's Transiting Exoplanet Survey Satellite (TESS). The newly detected alien world, designated TOI-5344 b is similar in size and mass to Saturn. The finding is reported.....»»
Old data from Kepler turns up a system with seven planets
NASA's Kepler mission ended in 2018 after more than nine years of fruitful planet-hunting. The space telescope discovered thousands of planets, many of which bear its name. But it also generated an enormous amount of data that exoplanet scientists ar.....»»
Scorching, seven-planet system revealed by new Kepler exoplanet list
A system of seven sweltering planets has been revealed by continued study of data from NASA's retired Kepler space telescope: Each one is bathed in more radiant heat from their host star per area than any planet in our solar system. Also unlike any o.....»»

New exoplanet-informed research sets clearer bounds on the search for radio technosignatures
In a new study published in The Astronomical Journal, researchers used the known population of exoplanets and extrapolated to the much larger, unknown population of exoplanets to set better thresholds for planetary effects on signals from ETIs (extra.....»»
Two Neptune-sized exoplanets discovered with TESS
An international team of astronomers reports the detection of two new exoplanets orbiting a bright star known as TOI-5126, using NASA's Transiting Exoplanet Survey Satellite (TESS). The newfound alien worlds are similar in size to the solar system's.....»»
This exoplanet might literally be the most metal planet out there
It's likely that something stripped the outer layers off a once-rocky exoplanet. Enlarge / Computer-generated conception of the hot, metal planet. (credit: NASA) Metals are everywhere in the Universe, from hot gas giants.....»»
The Milky Way May Be Missing a Trillion Suns" Worth of Mass
Slow-moving stars at the Milky Way’s outskirts suggest our galaxy may be far lighter than previously believed, with profound implications for dark matter.....»»
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.....»»
Possible hints of life found on distant planet. How excited should we be?
Data from the James Webb Space Telescope (JWST) has shown that an exoplanet around a star in the constellation Leo has some of the chemical markers that, on Earth, are associated with living organisms. But these are vague indications. So how likely i.....»»
James Webb sees evidence of an ocean-covered ‘Hycean’ exoplanet
James Webb has once again peered into the atmosphere of an exoplanet, and this time it has identified indications that the planet could be covered in ocean......»»
JWST accidentally discovers 21 brown dwarfs
When you launch humanity's most powerful telescope, you expect results. The JWST has delivered excellent results by detecting ancient galaxies, identifying chemicals in exoplanet atmospheres, and peering into star-forming regions with more detail and.....»»
If Earth were an exoplanet, JWST would know there"s an intelligent civilization here
If we're going to look for life on other worlds, why not start with the one planet we know has life? Earth's atmosphere is rich with oxygen and molecules such as methane, which strongly suggest the presence of life. It also has traces of molecules su.....»»
Saturday Citations: Ancient corvids, tetraquarks, and researchers who aren"t bored hearing about your dreams
This week, researchers reported on two-dimensional gold sheets, a tidy little meson made of four quarks (and its buddy!) and a big and almost unimaginably dense exoplanet with an exciting backstory......»»
Dense Neptune-sized exoplanet discovered with TESS
Using NASA's Transiting Exoplanet Survey Satellite (TESS), an international team of astronomers has discovered a new massive and dense exoplanet. The newfound alien world, designated TOI-332 b, is one of the densest Neptune-sized planets known to dat.....»»
"Thermometer" molecule confirmed on exoplanet WASP-31b
Chromium hydride (CrH), a molecule that's relatively rare and particularly sensitive to temperature, is useful as a "thermometer for stars," according to astronomer Laura Flagg, because it's abundant only in a narrow range between 1,200–2,000 degre.....»»
