These images, taken a year apart, show how supernova SN2018gv faded over time. The High-Latitude Time-Domain Survey by NASA’s Nancy Grace Roman Space Telescope will spot 1000s of supernovae, including a type that can be used to measure the universe's expansion.

NEWS: Will you be my neighbor? #NASAWebb has found strong evidence of a gas giant planet orbiting Alpha Centauri A, a star in the stellar system closest to our own sun: webbtelescope.pub/4oyLiQa 🔭 🧪

$Three panels, each showing a different view of the binary star system Alpha Centauri. The panel on the left is a Digitized Sky Survey image showing a single bright blue point source at the center of a black image with stars scattered throughout. The center of this source is outlined with a vertical box, tilted slightly to the left, with two diagonal lines leading to the second panel. The 2nd panel is a Hubble image that shows 2 white stars with 4 diffraction spikes each against a black background. The top star is labeled Alpha Cen B and the bottom Alpha Cen A. Alpha Cen A is outlined with a white square with 2 diagonal lines leading to the 3rd panel at the furthest right, which shows a Webb image of the star. An orange star icon and central black circle outlined in white marks the location of Alpha Cen A. A large white circle outlines a blurry red-toned field that surrounds the location of the star. A bright orange blob at 9 o’clock in relation to the star is labeled “S1” and circled.$

WELCOME TO THE FAMILY, ALPHA CEN A b!!!

First hinted at in Wagner+21, now Chas Beichman, Aniket Sanghi and team have published new JWST images of alpha Cen A showing another hint of this Saturn-sized planet candidate!

IPAC scientist finds evidence for a planet in the same star system as #Avatar 's Pandora!

If confirmed by additional observations, "Its very existence [...] would challenge our understanding of how planets form, survive, and evolve in chaotic environments."
