Faintest planet ever imaged from Earth found after more than 10 years of hide-and-seek
A team of astronomers has discovered a third planet orbiting the star Beta Pictoris. The new planet, Beta Pictoris d, is 100 times fainter than Beta Pictoris b—the first planet discovered in the same system—and is among the lightest exoplanets ever imaged from the ground. After s
Two 'super-puff' cotton candy exoplanets are the lightest gas giants ever discovered
Astronomers have discovered two "super-puff" exoplanets orbiting the same star that have densities lower than cotton candy, making them the lightest worlds ever seen.
China plans to double the size of its Tiangong space station while the ISS nears its end
China plans to add three new modules to Tiangong along with a co-orbiting space telescope, as the ISS heads for a Pacific splashdown.
Mars orbiter watches Perseverance rover cross the marathon finish line | Space photo of th
With the speed at which the rover completed this marathon, and how well it continues to explore on Mars, who knows, maybe Perseverance will be the first to manage an ultramarathon on the Red Planet.
Light pollution may be erasing millions of dollars in value at US dark-sky parks
Researchers combined satellite data and visitor surveys at dark-sky parks to quantify the economic value of dark skies amid rising light pollution.
America 250: How has telescope technology evolved since the dawn of the U.S.?
Optical telescopes have come a long way in the past two-and-a-half centuries — from the homemade telescope of William Herschel to the orbiting Hubble Space Telescope.
NASA’s TESS Mission Finds Planetary System in New Way
For the first time, NASA’s TESS (Transiting Exoplanet Survey Satellite) mission has identified a planet orbiting a distant star thanks to ripples in space-time. Unlike the star-hugging transiting planets TESS regularly reveals, the newfound world is a super-Jupiter orbiting far f
‘Just in time for Canada Day’: Spacewalking astronauts repair space station’s huge Canadar
Expedition 74 flight engineers Chris Williams and Jessica Meir conducted a seven-hour spacewalk to replace a wrist joint on the International Space Station's Canadarm2 robot arm on June 30, 2026.
The growing number of satellites in orbit could soon make telescopes obsolete. 'For astron
If the number of satellites in Earth's orbit exceeds 100,000, humanity may lose its ability to study the universe from the planet's surface. Some companies want to put millions into space.
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
