NASA’s Hubble Sees White Dwarf Eating Piece of Pluto-Like Object
2025.09.18
In our nearby stellar neighborhood, a burned-out star is snacking on a fragment of a Pluto-like object. With its unique ultraviolet capability, only NASA’s Hubble Space Telescope could identify that this meal is taking place. The stellar remnant is a white dwarf about half the mass of our Sun, but that is densely packed into […]

This scene is in the Large Magellanic Cloud, a dwarf galaxy situated about 160,000 light-years away in the constellations Dorado and Mensa. With a mass equal to 10–20% of the mass of the Milky Way, the Large Magellanic Cloud […]
NASA’s Webb Observes Immense Stellar Jet on Outskirts of Our Milky Way
2025.09.10
A blowtorch of seething gasses erupting from a volcanically growing monster star has been captured by NASA’s James Webb Space Telescope. Stretching across 8 light-years, the length of the stellar eruption is approximately twice the distance between our Sun and the next nearest stars, the Alpha Centauri system. The size and strength of this particular […]
Ami Choi: Unraveling the Invisible Universe
2025.09.09
Research Astrophysicist and Roman’s Deputy Wide Field Instrument Scientist – Goddard Space Flight Center From a young age, Ami Choi — now a research astrophysicist at NASA — was drawn to the vast and mysterious. By the fifth grade, she had narrowed her sights to two career paths: marine biology or astrophysics. “I’ve always been […]
NASA Webb Looks at Earth-Sized, Habitable-Zone Exoplanet TRAPPIST-1 e
2025.09.08
Scientists are in the midst of observing the exoplanet TRAPPIST-1 e with NASA’s James Webb Space Telescope. Careful analysis of the results so far presents several potential scenarios for what the planet’s atmosphere and surface may be like, as NASA science missions lay key groundwork to answer the question, “are we alone in the universe?” […]
Hubble Spies Galaxy with Lots to See
2025.09.05
While it may appear as just another spiral galaxy among billions in the universe, this image from the NASA/ESA Hubble Space Telescope reveals a galaxy with plenty to study. The galaxy, NGC 7456, is located over 51 million light-years away in the constellation Grus (the Crane). This Hubble image reveals fine detail in the galaxy’s […]
Glittering Glimpse of Star Birth From NASA’s Webb Telescope
2025.09.04
This is a sparkling scene of star birth captured by NASA’s James Webb Space Telescope. What appears to be a craggy, starlit mountaintop kissed by wispy clouds is actually a cosmic dust-scape being eaten away by the blistering winds and radiation of nearby, massive, infant stars. Called Pismis 24, this young star cluster resides in […]

NASA’s Hubble Uncovers Rare White Dwarf Merger Remnant
2025.08.13
An international team of astronomers has discovered a cosmic rarity: an ultra-massive white dwarf star resulting from a white dwarf merging with another star, rather than through the evolution of a single star. This discovery, made by NASA’s Hubble Space Telescope’s sensitive ultraviolet observations, suggests these rare white dwarfs may be more common than previously […]
Webb Narrows Atmospheric Possibilities for Earth-sized Exoplanet TRAPPIST-1 d
2025.08.13
The exoplanet TRAPPIST-1 d intrigues astronomers looking for possibly habitable worlds beyond our solar system because it is similar in size to Earth, rocky, and resides in an area around its star where liquid water on its surface is theoretically possible. But according to a new study using data from NASA’s James Webb Space Telescope, […]
