Scores of baby stars shrouded by dust are revealed in this infrared image of the star-forming region NGC 2174, as seen by NASA’s Spitzer Space Telescope. Some of the clouds in the region resemble the face of a monkey in visible-light images, hence the nebula’s nickname: the “Monkey Head.” However, in infrared images such as …

This Hubble Space Telescope image captures a portion of the reflection nebula IC 2631, which contains a protostar, the hot, dense core of a forming star that is accumulating gas and dust. Eventually, the protostar may gravitationally gather enough matter to begin nuclear fusion and emit its own energy and starlight.Reflection nebulae are clouds of …

This image of our home planet shows how Earth looked from more than 950,000 miles, or 1.5 million kilometers, away during the total solar eclipse visible in Antarctica on Dec. 4, 2021. The EPIC instrument on the DSCOVR spacecraft captured the eclipse’s umbra, the dark, inner shadow of planet Earth. Shaped like a cone extending …

Using the unique capabilities of NASA’s Hubble Space Telescope, a team of astronomers has discovered the most energetic outflows ever witnessed in the universe. They emanate from quasars and tear across interstellar space like tsunamis, wreaking havoc on the galaxies in which the quasars live. This illustration shows a distant galaxy with an active quasar …

A new trio of examples of ‘data sonification’ from NASA missions provides a new method to enjoy an arrangement of cosmic objects. Data sonification translates information collected by various NASA missions — such as the Chandra X-ray Observatory, Hubble Space Telescope, and Spitzer Space Telescope — into sounds. This image of the Bullet Cluster (officially …

An array of 960 microphones is seen here off the end of runway 11 at Boeing’s research facility near Glasgow, Montana. The microphones were used by NASA to record the sound of a low-flying 787-10 Dreamliner passing overhead as part of the Chicago-based company’s 2020 ecoDemonstrator program during late August and early September. NASA researchers …

The brightest stars embedded in nebulae throughout our galaxy pour out a torrent of radiation that eats into vast clouds of hydrogen gas – the raw material for building new stars. This etching process sculpts a fantasy landscape where human imagination can see all kinds of shapes and figures. This nebula in the constellation of …
