The Blaze Star isn’t one star but 2. It’s a binary system with a white dwarf and red giant. The Blaze Star’s white dwarf has built up material on its surface, siphoned off from the red giant star. Periodically, it “can’t take no more” and explodes, about every 80 years. Despite the powerful explosion, the … Read more
NEW ORLEANS — Solar sails that allow satellites to glide on the light from the sun could soon become a reality. The technology would allow scientists to provide earlier warnings of space weather events such as geomagnetic storms, which have the potential to disrupt technological systems on Earth. “A lot of us have experienced sailing; … Read more
It is not unusual to see a Saturn V launch while viewing a film at Space Center Houston. Never before, though, has that spectacle stretched beyond the center’s five-story-tall screen to fill the theater’s walls and extend out onto the floor. That is what happens now with the premiere of “The Moonwalkers: A Journey with … Read more

View larger. | In this image from Voyager 1 – acquired on February 14, 1990, from a distance slightly past the orbit of Saturn – planet Earth appears as a pale blue dot within the sunbeam, just right of center. As you can see, the blue glow of Earth occupies less than a single pixel … Read more
View larger. | Artist’s illustration of Cassini spacecraft flying through the water vapor plumes of Enceladus. A new study from researchers in the UK has found that Enceladus’ subsurface ocean might have layers that make it difficult to find traces of life on Enceladus.

Is it a bird? Is it a plane? No, it’s super Neptune! But this Superman-mimicking planet is not blasting through space on its own. It is being dragged along by its parent star. NASA scientists have discovered what they suspect is the hypervelocity star racing through space with a Neptune-like planet in tow. The system … Read more
Sometimes, things across the vast Universe line up just right for us. The Einstein Ring above, like all Einstein Rings, has three parts. In the foreground is a distant massive object like a galaxy or galaxy cluster. In the background, at an even greater distance away, is a star or another galaxy. We’re the observers, … Read more
This is the optical module of the telescope KM3NeT that has captured the highest energy neutrino yet known. It made the discovery from the dark depths of the bottom of the Mediterranean Sea. Image via KM3NeT (CC BY-NC 4.0). Highest energy neutrino observed from undersea telescope There’s a telescope sitting more than a mile and … Read more
Look closely. Can you spot the ring of light around the center of this galaxy, NGC 6505? ESA’s Euclid telescope captured galaxy NGC 6505, which is acting as a gravitational lens, bending the light from a more distant galaxy and creating this Einstein ring. See closeup below. Image via ESA/ Euclid/ Euclid Consortium/ NASA. Image … Read more
