Direct link Three Dwarf Spheroidal Galaxies Are Found to Rotate

28 Jul 2021, 01:10 UTC 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.

Direct link Hubble Finds First Evidence of Water Vapor at Jupiter’s Moon Ganymede

26 Jul 2021, 15:00 UTC 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.

Direct link Martian Global Dust Storm Ended Winter Early in the South

23 Jul 2021, 12:43 UTC A dust storm that engulfed the entire Red Planet in 2018 destroyed a vortex of cold air around the Martian south pole and brought an early spring to the hemisphere.

Direct link Hubble Views a Faraway Galaxy Through a Cosmic Lens

23 Jul 2021, 12:30 UTC The center of this image from the NASA/ESA Hubble Space Telescope is framed by the tell-tale arcs that result from strong gravitational lensing, a striking astronomical phenomenon which can warp, magnify, or even duplicate the appearance of distant galaxies

Direct link Astronomers make first clear detection of a moon-forming disc around an exoplanet

22 Jul 2021, 12:00 UTC Using the Atacama Large Millimetre/submillimeter Array (ALMA), in which the European Southern Observatory (ESO) is a partner, astronomers have unambiguously detected the presence of a disc around a planet outside our Solar System for the first time. The observations will shed new light on how moons and planets form in young stellar systems.

21 Jul 2021, 16:45 UTC NASA is making final preparations for its Perseverance Mars rover to collect its first-ever sample of Martian rock, which future planned missions will transport to Earth. The six-wheeled geologist is searching for a scientifically interesting target in a part of Jezero Crater called the “Cratered Floor Fractured Rough.”
