Maybe the Elusive Planet 9 Doesn’t Exist After All Oh Planet Nine, when will you stop toying with us? Whether you call it Planet Nine, Planet X, the Perturber, Jehoshaphat, “Phattie,” or any of the other proposed names—either serious or flippant—this scientific back and forth over its existence is getting exhausting. Is this what it […]
SN4, We Hardly Knew You. Another Starship Prototype Lost! SpaceX suffered yet another setback when their SN4 prototype exploded into a fireball during a static fire test of its single Raptor engine.

Mars Doesn’t Have Much of a Magnetosphere, But Here’s a Map Even though Earthling scientists are studying Mars intently, it’s still a mysterious place. One of the striking things about Mars is all of the evidence, clearly visible on its surface, that it harbored liquid water. Now, all that water is gone, and in fact, […]
Mergers between galaxies trigger activity in their core Active galactic nuclei (AGNs) play a major role in galaxy evolution. Astronomers from SRON and RuG have now used a record-setting sample of galaxies to confirm that galaxy mergers have a positive effect on igniting AGNs. They were able to compile about 10 times more pictures of […]
A New Kind of Supernova Explosion has been Discovered: Fast Blue Optical Transients For the child inside all of us space-enthusiasts, there might be nothing better than discovering a new type of explosion. (Except maybe bigger rockets.) And it looks like that’s what’s happened. Three objects discovered separately—one in 2016 and two in 2018—add up […]
How to Make the Food and Water Mars-Bound Astronauts Will Need for Their Mission New technologies are being developed that will ensure astronauts have plenty of drinking water and food wherever resupply missions are not readily available The post How to Make the Food and Water Mars-Bound Astronauts Will Need for Their Mission appeared first […]
Powerful Telescope Confirms There’s an Earth-Sized World Orbiting Proxima Centauri There is an Earth-sized planet only four light years from Earth. Whether it has life is yet to be known.

On Mars, mud flows like lava One of the most striking features on Earth are the curious flows of lava as it cools, forming undulating ropes of rock known by the Hawaiian word pahoehoe. New research simulating conditions on Mars now reveals that the red planet has its own kind of pahoehoe…but made of mud. […]
This Rocket Engine’s Thrust Chamber was 3D-printed and Only has Three Parts This week, European engineers hot-fire tested a fully 3D-printed thrust chamber that could one day power the upper stages for rockets. The chamber has just three parts, and was constructed using additive layer manufacturing, another name for 3D printing. This hot-fire test […]
At cosmic distances, even the speed of light is really slow The speed of light is the absolute fastest thing in the universe, clocking in at a whopping 299,792,458 meters per second. At that speed, a beam of light could travel around the Earth’s entire equator in a mere 0.13 seconds. That’s…fast. And yet, when […]
Image: Hubble grabs a stellar latte Far away in the Ursa Major constellation is a swirling galaxy that would not look out of place on a coffee made by a starry-eyed barista. NGC 3895 is a barred spiral galaxy that was first spotted by William Herschel in 1790 and was later observed by the NASA/ESA […]
MAXI J1820+070: Black hole outburst caught on video Astronomers have caught a black hole hurling hot material into space at close to the speed of light. This flare-up was captured in a new movie from NASA’s Chandra X-ray Observatory. phys.org Go to Source
Astronomers predict bombardment from asteroids and comets in other planetary system The planetary system around star HR8799 is remarkably similar to our solar system. It has four gas giants in between two asteroid belts. A research team led by RuG and SRON used this similarity to model the delivery of materials by asteroids, comets and […]
In planet formation, it’s location, location, location Astronomers using NASA’s Hubble Space Telescope are finding that planets have a tough time forming in the rough-and-tumble central region of the massive, crowded star cluster Westerlund 2. Located 20,000 light-years away, Westerlund 2 is a unique laboratory to study stellar evolutionary processes because it’s relatively nearby, quite […]
Extremely Hot Exoplanets Can Have Extreme Weather, Like Clouds of Aluminum Oxide and Titanium Rain Thanks to the success of the Kepler mission, we know that there are multitudes of exoplanets of a type called “Hot Jupiters.” These are gas giants that orbit so close to their stars that they reach extremely high temperatures. They […]
Extremely intense radio burst detected from magnetar SGR 1935+2154 Using the Canadian Hydrogen Intensity Mapping Experiment (CHIME) radio telescope, astronomers have detected a bright, millisecond-duration radio burst from a galactic magnetar known as SGR 1935+2154. The discovery of such an extremely intense event, reported in a paper published May 20, could be important for improving […]
ESPRESSO confirms the presence of an Earth-sized planet around the nearest star (Update) The existence of a planet the size of Earth around the closest star to the Sun, Proxima Centauri, has been confirmed by an international team of scientists including researchers from the University of Geneva (UNIGE). The results, published in Astronomy & Astrophysics, […]
