    The International Space Station is seeing "floating" in space with Earth in its background.

    The International Space Station is 20 and going strong

    20 years ago, three astronauts stepped aboard the ISS. It’s since hosted residents from many countries, creating humanity’s first history of living in space.

    Ancient life signs under dinosaur-killing Chicxulub crater

    Researchers have found evidence for an ancient microbial ecosystem in a hydrothermal system beneath Mexico’s Chicxulub Crater, thought to be the site of the impact that killed the dinosaurs 66 million years ago.

    The sun is becoming active again

    EarthSky community members have captured the giant sunspot region – AR 2781 – currently making its way across the sun’s visible surface.

    Hubble telescope reveals asteroid Psyche’s rusty surface

    Scientists already had Psyche classified as a metallic asteroid, but new observations with the Hubble telescope reveal its rusty surface and provide scientists with a unique view into what Earth-like planets are like during their formation.

    NASA re-establishes contact with Voyager 2 spacecraft

    On October 29, NASA re-established contact with its Voyager 2 spacecraft, after the probe was left flying solo for 7 months while repairs were made to the radio antenna in Australia used to control it.

    How Jupiter’s moon Io gets its hellish atmosphere

    Hot, active volcanoes produce almost half of Jupiter’s moon Io’s sulfur atmosphere, according to new observations using the ALMA telescope. The rest comes from cold sulfur deposits that freeze on the surface, then sublimate in sunlight.

    The Starship spacecraft is seen towering over onlookers with a clear sky backdrop.

    SpaceX Starship as a trash collector in Earth orbit?

    SpaceX Starship’s many tasks may include launching humans into space, carrying satellites into orbit and — perhaps — removing troublesome pieces of space debris.

    The year's third and final conjunction of Jupiter and Pluto takes place on December 12, 2020.

    Jupiter gives us Pluto in 2020

    The 3rd of this year’s 3 Jupiter-Pluto conjunctions is coming up on November 12, 2020. Jupiter won’t have another conjunction with Pluto again until February 4, 2033. And another one this good? Not for centuries.

    Animation of the orbits of Earth and Apophis.

    Infamous asteroid Apophis is accelerating

    Astronomers in Hawaii have detected the Yarkovsky effect – a minuscule push imparted by sunlight – for asteroid Apophis. The effect is particularly important for Apophis, because it relates to the possibility of an Earth impact in 2068.

    Life-hunting Perseverance rover is halfway to Mars

    NASA announced that its Perseverance rover mission – which will search for evidence of ancient microbial life on Mars – has now passed the halfway mark in its journey to the planet.

    Astronomers release a black hole family portrait

    “Black hole family portrait” is a fancy way of saying “new catalog.” But it’s a very important and exciting catalog, released October 28, 2020, by gravitational wave astronomers, containing 39 new signals from black hole or neutron star collisions.

    Electric! Astronomers find sprites in Jupiter’s atmosphere

    Scientists with NASA’s Juno mission say they have detected sprites or elves – electrical phenomena above thunderstorms on Earth – in the clouds of Jupiter for the first time. Unlike the red-colored earthly ones however, the Jovian ones are blue.

    The magnetic fields of a jellyfish galaxy

    New work reveals the intricate relationship between so-called jellyfish galaxies, and the magnetic environment through which they move.

    Lighting a path to find Planet Nine

    The search for Planet Nine – a hypothesized 9th planet in our solar system – may come down to pinpointing the faintest orbital trails in an incredibly dark corner of space.

    SOFIA finds water on the moon’s sunlit surface

    For the first time ever, scientists have identified water on the moon’s sunlit surface, using SOFIA, an airborne observatory. Water on the moon also appears more widespread than previously thought.

    What astronauts think about life away from Earth

    Axiom is an aerospace company making new possibilities accessible to humanity. Watch as astronauts retell their experience launching from Earth and living in space.

    Super-Earth and sub-Neptune found orbiting a red dwarf star

    Astronomers using a telescope in Mexico have found two more exoplanets – a super-Earth and a sub-Neptune – orbiting a red dwarf star 120 light-years from Earth.

    How the world came to understand black holes

    Earlier this month, Roger Penrose, Reinhard Genzel, and Andrea Ghez split the 2020 physics Nobel Prize for decades of work on black holes. Click here to learn more about their monumental achievement and about the history of our understanding of these exotic objects in space.

    Betelgeuse is smaller, closer, and won’t explode any time soon

    According to new research, the red supergiant star Betelgeuse – which began to dim dramatically in brightness in late 2019 – might not explode for another 100,000 years. The star is also smaller and closer to us than first thought.
