New research suggests a rocky “lava planet” orbiting very close to its star likely carries an atmosphere. Astronomers found an atmosphere where they least expected it—clinging to an exoplanet that’s ...

A tightly orbiting planet in another star system is overturning long held ideas about what small, super heated worlds can keep around them. TOI 561 b circles its star in less than half a day and faces ...

A rocky exoplanet outside the Earth's solar system may have an atmosphere, according to new evidence gathered by NASA researchers. The exoplanet, known as super-Earth TOI-561b, was discovered in 2020, ...

Caption: An emission spectrum captured by NIRSpec (the Near-Infrared Spectrograph) on NASA’s James Webb Space Telescope in May 2024 shows the brightness of different wavelengths of 3- to 5-micron ...

A molten lava world cloaked in a thick envelope of vaporized rock could be the strongest evidence we have yet of a rocky exoplanet with an atmosphere beyond our Solar System. The planet TOI-561 b is ...

Exoplanet TOI-561 b is the closest of four worlds orbiting a 10-billion-year-old G-type star roughly 280 light-years from Earth. - NASA / ESA / CSA / Ralf Crawford illustration NASA’s James Webb Space ...

Scientists have discovered the strongest evidence yet of a rocky planet with an atmosphere outside the solar system, challenging previous notions that small planets that orbit closely to their stars ...

Caption: This artist’s concept shows what the ultra-hot super-Earth exoplanet TOI-561 b could look like based on observations from NASA’s James Webb Space Telescope and other observatories. Webb data ...
