Astronomers using NASA’s Hubble Space Telescope observed the smallest exoplanet where water vapor has been detected in the atmosphere. At only approximately twice Earth’s diameter, the planet GJ 9827d could be an example of potential planets with water-rich atmospheres elsewhere in our galaxy.

A barred spiral galaxy and a lenticular galaxy come together to create this interacting pair known as Arp 140. The lenticular galaxy, NGC 274, is visible on the right side of this new NASA Hubble Space Telescope image, and the barred spiral, NGC 275, is at left. The twosome is located in the constellation Cetus.  Lenticular […]

This new NASA Hubble Space Telescope image shows a group of interacting galaxies known as LEDA 60847. LEDA 60847 is classified as an active galactic nuclei, or AGN. An AGN has a supermassive black hole in the galaxy’s central region that is accreting material. The AGN emits radiation across the entire electromagnetic spectrum and shines […]

The U.S. Postal Service has issued two new Priority Mail stamps celebrating NASA’s James Webb Space Telescope, the largest, most powerful, and most complex telescope ever put in space. The stamps, issued Jan. 22, feature images of the cosmos captured by Webb since it began its science mission in 2022. Webb is a mission led […]

Arp 300 consists of two interacting galaxies, UGC 05028 (the smaller face-on spiral galaxy) and UGC 05029 (the larger face-on spiral). Likely due to its gravitational dance with its larger partner, UGC 05028 has an asymmetric, irregular structure, which is not as visible from ground-based telescopes but is quite distinct in this new image from […]

Researchers analyzing images from NASA’s James Webb Space Telescope have found that galaxies in the early universe are often flat and elongated, like surfboards and pool noodles – and are rarely round, like volleyballs or frisbees. “Roughly 50 to 80% of the galaxies we studied appear to be flattened in two dimensions,” explained lead author […]
