The galaxy JW100 (lower right) features prominently in this image from the NASA/ESA Hubble Space Telescope. The streams of star-forming gas dripping from the disk of the galaxy like streaks of fresh paint are formed by a process called ram pressure stripping. Their resemblance to dangling tentacles led astronomers to refer to JW100 as a ‘jellyfish’ galaxy. JW100 is over 800 million light-years away, in the constellation Pegasus.

There’s a cosmic jellyfish in this week’s Hubble image

Jellyfish galaxies have a main body of stars, with tentacle-like structures reaching off away from the body in just one direction.

An artist’s depiction of the interstellar comet ‘Oumuamua, as it warmed up in its approach to the sun and outgassed hydrogen (white mist), which slightly altered its orbit. The comet, which is most likely pancake-shaped, is the first known object other than dust grains to visit our solar system from another star.

We now know what caused comet ‘Oumuamua’s strange orbit

It wasn't aliens that sent an interstellar comet to visit our solar system. The explanation is a phenomenon called outgassing.
This artist’s illustration shows the ejection of a cloud of debris after NASA’s DART spacecraft collided with the asteroid Dimorphos. The image was created with the help of the close-up photographs of Dimorphos that the DRACO camera on the DART spacecraft took right before the impact. The DART spacecraft collided with Dimorphos at a speed of over 6 kilometres per second (about 22 000 kilometres per hour). After the impact several telescopes observed the evolution of the cloud of debris, including ESO’s Very Large Telescope.

When NASA crashed a spacecraft into an asteroid, it wasn't only a thrilling test of planetary defense. It was also a unique opportunity for scientists.
This illustration conceptualises the swirling clouds identified by the James Webb Space Telescope in the atmosphere of the exoplanet VHS 1256 b. The planet is about 40 light-years away and orbits two stars that are locked in their own tight rotation. Its clouds, which are filled with silicate dust, are constantly rising, mixing, and moving during its 22-hour day.

Exoplanet VHS 1256 b, around 40 light-years away, has an unusual atmosphere where clouds of sand float in temperatures of 1,500 degrees Fahrenheit.
[Jupiter: left] - The forecast for Jupiter is for stormy weather at low northern latitudes. A prominent string of alternating storms is visible, forming a ‘vortex street’ as some planetary astronomers call it. [Uranus: right] - Uranus’s north pole shows a thickened photochemical haze that looks similar to the smog over cities. Several little storms can be seen near the edge of the polar haze boundary. Note: The planets do not appear in this image to scale.

Some exoplanets have one side permanently facing their star while the other side is in perpetual darkness. The ring-shaped border between these permanent day and night regions is called a “terminator zone.” In a new paper in The Astrophysical Journal, physics and astronomy researchers at UC Irvine say this area has the potential to support extraterrestrial life.

Tidally locked exoplanets could be habitable in the ‘terminator zone’

There are exoplanets where one side is always in sunlight and the other is always dark. But a particular region of these planets could be habitable.
This image shows just a portion of M55, the cluster as a whole appears spherical because the stars’ intense gravitational attraction pulls them together. Hubble’s clear view above Earth’s atmosphere resolves individual stars in this cluster. Ground-based telescopes can also resolve individual stars in M55, but fewer stars are visible.
