CHEOPS finds unique planetary system
Jan 26, 2021 (SPX)
When one planet takes three days to orbit its star and its neighbor takes two days, for example. Using the CHEOPS space telescope, scientists, led by astrophysi...
Puzzling six-exoplanet system with rhythmic movement challenges theories of how planets form
Jan 26, 2021 (SPX)
The first time the team observed TOI-178, a star some 200 light-years away in the constellation of Sculptor, they thought they had spotted two planets going aro...
The 7 rocky TRAPPIST-1 planets may be made of similar stuff
Jan 25, 2021 (JPL)
A new study published in the Planetary Science Journal shows that the TRAPPIST-1 planets have remarkably similar densities. That could mean they all contain abo...
The seven rocky planets of TRAPPIST-1 seem to have very similar compositions
Jan 25, 2021 (SPX)
The TRAPPIST-1 system is home to the largest number of planets similar in size to our Earth ever found outside our solar system. Discovered in 2016 by a researc...
Holding the system of HR 8799 together
Jan 25, 2021 (SPX)
The direct imaging technique involves taking an image of a star and removing all the light associated with the star to see what remains (hopefully planets!). Wh...
Solar system formation in two steps
Jan 22, 2021 (SPX)
Their findings will be published in Science (Friday 22 January 2021; under embargo until 2pm US Eastern Time Thursday 21 January 2021). The paper presents a new...
Astronomers discover first cloudless, Jupiter-like planet
Jan 22, 2021 (SPX)
Named WASP-62b, the gas giant was first detected in 2012 through the Wide Angle Search for Planets (WASP) South survey. Its atmosphere, however, had never been ...
Two-step formation explains our solar system's dichotomy of planets
Jan 21, 2021 (UPI)
According to a study published Thursday in the journal Science, this divide is best explained by a two-step formation process. Over the last few decades, scient...
A 'super-puff' planet like no other
Jan 19, 2021 (SPX)
This intriguing discovery by Ph.D. student Caroline Piaulet of UdeM's Institute for Research on Exoplanets (iREx) suggests that gas-giant planets form a lot mor...
Simulating evolution to understand a hidden switch
Jan 19, 2021 (SPX)
Tomato hornworm larvae are green in warmer regions, making camouflage easier, but black in cooler temperatures so that they can absorb more sunlight. This pheno...
Astronomers finally measure polarized light from exoplanet
Jan 13, 2021 (SPX)
The discovery concerns the exoplanet DH Tau b. This is a very young planet of only 2 million years old at 437 light years from Earth in the constellation Taurus...
A rocky planet around one of our galaxy's oldest stars
Jan 12, 2021 (SPX)
The planet orbits the star TESS Object of Interest (TOI) 561, named for the ongoing NASA TESS planet hunting mission. TOI-561 belongs to a rare population of st...
Astronomers measure enormous planet lurking far from its star
Jan 12, 2021 (SPX)
The planet is roughly five times heavier than Jupiter, hence its nickname GOT 'EM-1b, which stands for Giant Outer Transiting Exoplanet Mass. Though it is nearl...
Astronomers find evidence for planets shrinking over billions of years
Jan 12, 2021 (SPX)
From centuries of studying the planets within our solar system, astronomers have wondered how planets form and evolve to become the ones we observe them today. ...
A Tale of Planetary Resurrection
Jan 12, 2021 (SPX)
Now, David Ciardi, chief scientist of NASA's Exoplanet Science Institute (NExScI), located at Caltech's IPAC, says he has "resurrected KOI-5Ab from the dead," t...
Discovery boosts theory that life on Earth arose from RNA-DNA mix
Dec 31, 2020 (SPX)
In a study published in the chemistry journal Angewandte Chemie, they demonstrated that a simple compound called diamidophosphate (DAP), which was plausibly pre...
Key building block for organic molecules discovered in meteorites
Dec 21, 2020 (SPX)
The chemistry of life runs on organic compounds, molecules containing carbon and hydrogen, which also may include oxygen, nitrogen and other elements. While com...
Astronomers detect possible radio emission from exoplanet
Dec 17, 2020 (SPX)
The team, led by Cornell postdoctoral researcher Jake D. Turner, Philippe Zarka of the Observatoire de Paris - Paris Sciences et Lettres University and Jean-Mat...
Device mimics life's first steps in outer space
Dec 16, 2020 (SPX)
In an article published in Review of Scientific Instruments, by AIP Publishing, the scientists detail how VENUS - an acronym of the French phrase "Vers de Nouve...
Scientists discover compounds that could have helped to start life on Earth
Dec 15, 2020 (SPX)
Only in this case could phosphorus be involved in phosphorylation, which enables the synthesis of complex molecules. However, phosphorus in nature is only found...
