This weird 'hot Jupiter' exoplanet has a hotspot in the wrong place, and astronomers aren'
Astronomers have discovered a curious new exoplanet that challenges assumptions about hot Jupiters, some of the most extreme planets in the universe.
Good Morning, Earth!
NASA astronaut Chris Williams took this photo of an orbital sunrise from the International Space Station on June 26, 2026. In 24 hours, the space station makes 16 orbits of Earth, traveling through 16 sunrises and sunsets. Learn more about the orbiting laboratory. Image credit: N
Astronomers discover a potentially habitable planet just 25 light-years away. 'This one is
Astronomers discovered a planet 25 light-years away that orbits within the habitable zone of its star that could potentially support liquid water and possibly life.
Getting Vikram-1 to orbit: Inside Skyroot Aerospace's coming bid to make spaceflight histo
Backed by a $1.1 billion valuation, Skyroot Aerospace is betting that its Vikram-1 rocket can help transform India's commercial launch industry. And Vikram-1 is set to fly soon.
Hubble Sees Crimson Cloud and Stars
Blue and white stars shine brilliantly against a crimson background of glowing gas in this July 3, 2026, image of stellar nursery LH 95 from NASA’s Hubble Space Telescope. LH 95 is a region in the Large Magellanic Cloud, a dwarf galaxy that orbits the Milky Way. Low-mass infant s
Ancient stellar flyby may still be steering long-period comets today
The Gaia mission has allowed researchers to understand the motions of stars like never before, even revealing possible interactions between our solar system and nearby stars. Planetary Science Institute Senior Scientist Nathan Kaib and collaborator Sean Raymond (Universite de Bor
A single origin story for the Milky Way's most mysterious stars
Lurking at the heart of the Milky Way, Sagittarius A* (Sgr A*) is a supermassive black hole four million times the mass of the sun, surrounded by a puzzling collection of young, massive stars whose orbits have long defied explanation. Astronomers have proposed various competing t
Nearby 'Super Earth' may be a better candidate for life than previously thought
Using the Hobby-Eberly Telescope at McDonald Observatory, astronomers have taken a closer look at a nearby exoplanet and discovered it may be more Earth-like than previously thought. The planet, known as GJ 3378b, orbits a small, cool star called a red dwarf. Just 25 light-years
Scientists discover rare 'super-Jupiter' planet with 180-day long orbit
Scientists from Queen's University Belfast have led an international team in the discovery of a rare new planet, which is larger than Jupiter and orbits a distant star every 180 days. Named NGTS-38 b, it is an exoplanet—a planet that orbits a star beyond our solar system. It is a
