An international team of astrophysicists has discovered the presence of transverse rotation in three dwarf spheroidal galaxies, a very faint type of galaxies and difficult to observe, which are orbiting round the Milky Way; this helps to trace their evolutionary history.

For the first time, astronomers have uncovered evidence of water vapor in the atmosphere of Jupiter's moon Ganymede. This water vapor forms when ice from the moon's surface sublimates -- that is, turns from solid to gas.

Hubble observations from the past two decades have been recently re-examined as a way of investigating what is happening in the tenuous atmosphere of Ganymede, the largest moon in the Solar System. It was in 1998 that the telescope’s Space Telescope Imaging Spectrograph took the first images of Ganymede at ultraviolet wavelengths, showing auroral bands — ribbons of electrified gas — that reinforced earlier evidence that the moon had a weak magnetic field. Now we have news of sublimated water vapor within the atmosphere, an earlier prediction now verified.

A clip from The Tonight Show with Johnny Carson in 1978 made the social media rounds in mid-July. The guest that episode—astronomer and science educator Carl Sagan—offered astute criticisms of the then recently released Star Wars film for its myopic (and whitewashed) imagining of how organisms from other galaxies might look. In this collection, reporter Leonard David examines the government report published in June that surveys our evidence for extraterrestrial life so far (see “Experts Weigh in on Pentagon UFO Report”), and two of our opinion writers contemplate some specific circumstances for alien contact.

Dark matter remains one of the greatest mysteries in science. Despite decades of astronomical evidence for its existence, no one has yet been able to find any sign of it closer to home. There have been dozens of efforts to do so, and one of the most prominent just hit a milestone – the release and analysis of 8 years of data. The IceCube Neutrino Observatory will soon be releasing results from those 8 years, but for now let’s dive in to what exactly they are looking for.

A team of astronomers have calculated how the intensity of the sun's solar wind will evolve over the next 5-billion-or-so years, when our star runs out of hydrogen fuel to burn and balloons into a tremendous red giant.

On Feb. 18th, 2021, NASA’s Perseverance rover landed within the Jezero Crater on Mars. Like its predecessor, Curiosity, a fellow member of NASA’s Mars Exploration Program (MEP), the goal of Perseverance is to seek out evidence of possible life on Mars (past and present). A key part of this mission will be the first sample return ever performed on Mars, where samples obtained by Perseverance will be placed in a cache for later retrieval and return to Earth.
