James Webb Space Telescope (JWST)
NASA’s James Webb Space Telescope captured two nearby dwarf galaxies interacting with each other in this image released on Dec. 2, 2025. Dwarf galaxies can give us insights into galaxies in the early universe, which were thought to have less mass than galaxies like the Milky Way, and also contain a lot of gas, relatively […]

Launched in March, NASA’s SPHEREx space telescope has completed its first infrared map of the entire sky in 102 colors. While not visible to the human eye, these 102 infrared wavelengths of light are prevalent in the cosmos, and observing the entire sky this way enables scientists to answer big questions, including how a dramatic […]

Hubble Space Telescope
This NASA/ESA Hubble Space Telescope image features a galaxy that’s hard to categorize. The galaxy in question is NGC 2775, which lies 67 million light-years away in the constellation Cancer (the Crab). NGC 2775 sports a smooth, featureless center that is devoid of gas, resembling an elliptical galaxy. It also has a dusty ring with patchy star […]

Lee esta nota de prensa en español aqui. A team of researchers has confirmed stars ring loud and clear in a “key” that will harmonize well with the science goals and capabilities of NASA’s upcoming Nancy Grace Roman Space Telescope. Stars’ turbulent natures produce waves that cause fluctuations in their overall brightness. By studying these […]
