A beautiful new image of Jupiter from the Hubble Space Telescope – captured in August 2020 – shows the planet’s icy moon Europa as well as several famous storms in Jupiter’s atmosphere.

A unique and exciting detail of Hubble’s snapshot appears at mid-northern latitudes as a bright, white, stretched-out storm traveling around the planet at 350 mph. Hubble shows that the Great Red Spot, rolling counterclockwise in the planet’s southern hemisphere, is plowing into the clouds ahead of it, forming a cascade of white and beige ribbons. Jupiter’s icy moon Europa, thought to hold potential ingredients for life, is visible to the left of the gas giant. Image via NASA, ESA, STScI, A. Simon (Goddard Space Flight Center), M.H.

For the first time, astronomers have detected a planet orbiting a white dwarf star. If further confirmed, the discovery shows that some planets could survive the destruction of their sun-like stars, and some might even remain potentially habitable.

. | Across a wide swath of the U.S. now, the sky looks hazy, and the sun look redder than usual,due to the wildfires in the U.S. West. Nancy Ricigliano on Long Island, New York caught this image on September 16, 2020 and wrote: "This is a result from the smoke from the wildfires that have reached so many places, including New York. This photo was taken at Jones Beach, Pier 10. Normally at this time, you can't even take a picture of the sun without a filter." Thank you, Nancy.
White dwarfs are dead stars. A single white dwarf contains roughly the mass of our sun in a volume no bigger than our planet. Our sun will become a white dwarf someday.
. | The Ring Nebula (M57) in the constellation Lyra shows the final stages of a star like our sun. The white dot in the center of this nebula is a white dwarf; it's lighting up the receding cloud of gas that once made up the star. The colors identify various elements like hydrogen, helium, and oxygen. Image via The Hubble Heritage Team (AURA/ STScI/ NASA
