The upper atmosphere of Jupiter is hotter than expected from the amount of sunlight that it receives: the average temperature should be about minus 73...
New research shows that mean annual temperatures in southeast Australia gradually declined from 27 degrees Celsius during the Middle Eocene epoch to...
Astronomers using ESO’s Very Large Telescope have detected the isotopically substituted carbon monoxide, 13CO, in the atmosphere of the young giant exoplanet...
Jupiter’s icy satellite Ganymede is the largest moon in the Solar System. Water ice on its surface is frozen solid in frigid temperatures as low as minus...
The ‘methane mystery’ on Mars has been ongoing for many years, with contradictory findings from seveal missions, wuch as ESA’s Mars Express and NASA’s...
Venus is well known for its rotating upper atmosphere, which sweeps around the planet once every 4 Earth days. This is in stark contrast to the rotation...
Astronomers using NASA’s Transiting Exoplanet Survey Satellite (TESS) have discovered four exoplanets orbiting TOI-2076 and TOI-1807, a pair of related...
In 2020, planetary scientists detected small amounts of the biosignature gas phosphine (PH3) in the atmosphere of Venus using the James Clerk Maxwell Telescope...
The Tunable Laser Spectrometer (TLS) in the Sample Analysis at Mars (SAM) chemistry lab onboard NASA’s Curiosity rover has detected atmospheric methane...
The recent suggestion of phosphine gas in the atmosphere of Venus has regenerated interest in the idea of life in clouds; however, such analyses usually...
Astronomers using NASA’s Transiting Exoplanet Survey Satellite (TESS) have discovered a temperate, Neptune-sized planet orbiting the M-dwarf star TOI-1231.
An...
In March 2021, NASA’s Curiosity rover observed clouds made of carbon dioxide (CO2) ice at high altitudes in the atmosphere of Mars.
Curiosity captured...
Jupiter, Saturn and numerous giant exoplanets discovered to date consist mostly of hydrogen and helium. In 1977, planetary scientists predicted the existence...
Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have produced a detailed map of intensity and abundance of gaseous hydrogen cyanide...
Atmospheric oxygen is thought to have played a vital role in the evolution of complex multicellular organisms. The so-called oxygen control hypothesis...
Three images of Jupiter from the 8-m Frederick C. Gillett Gemini North telescope at the Gemini Observatory and the NASA/ESA Hubble Space Telescope show...
Astronomers using NASA’s Transiting Exoplanet Survey Satellite have discovered a sub-Neptune exoplanet orbiting TOI-220, a bright and old K-type dwarf...
On July 11, 2020, NASA’s Parker Solar Probe made its third flyby of Venus. During 7 min around the closest approach, one of the spacecraft’s scientific...
Mars is cold today but once had water lakes and flowing rivers. The early warm climate cannot be explained by basic models of the early Mars greenhouse...
