This illustration of the newly forming exoplanet PDS 70b shows how material may be falling onto the giant world as it builds up mass. By employing Hubble’s ultraviolet light (UV) sensitivity, researchers got a unique look at radiation from extremely hot gas falling onto the planet, allowing them to directly […]

In celebration of the 31st anniversary of the launching of NASA’s Hubble Space Telescope, astronomers aimed the renowned observatory at a brilliant “celebrity star,” one of the brightest stars seen in our galaxy, surrounded by a glowing halo of gas and dust.

These four images taken by NASA’s Hubble Space Telescope reveal the chaotic birth of stars in the Orion complex, the nearest major star-forming region to Earth. The protostars were photographed in near-infrared light by Hubble’s Wide Field Camera 3. The images were taken November 14, 2009, and January 25, February […]

This is the compass image for VY Canis Majoris, showing the orientation and filters used. Credit: NASA, ESA, and R. Humphreys (University of Minnesota), and J. Olmsted (STScI) The red hypergiant VY Canis Majoris is enshrouded in huge clouds of dust Stars come in an extraordinary range of sizes. One […]

Trojan Asteroid 2019 LD2. Credit: NASA, ESA, STScI, B. Bolin IPAC/Caltech) Comet Comes in from the Cold and Finds an Off-Ramp on Its Sunward Journey Long road trips can be tedious and boring. That’s why many road travelers break up their arduous journey by making rest stops along the way. […]

This composite image illustrates the possibility of a Roman Space Telescope “ultra deep field” observation. In a deep field, astronomers collect light from a patch of sky for an extended period of time to reveal the faintest and most distant objects. This view centers on the Hubble Ultra Deep Field […]

Evidence indicates that large amounts of cosmic dust are produced as the stellar winds of massive stars collide in Wolf-Rayet binary or multiple-star systems. As the stars orbit each other and dust is produced, a distinctive pinwheel pattern is formed, as shown in this image from the European Southern Observatory. […]

This artist’s illustration shows NASA’s New Horizons spacecraft in the outer solar system. In the background lies the Sun and a glowing band representing zodiacal light, caused by sunlight reflecting off of dust. By traveling beyond the inner solar system and its accompanying light pollution, New Horizons was able to […]
