Every day, the sun ejects large amounts of a hot particle soup known as plasma toward Earth where it can disrupt telecommunications satellites and damage electrical grids. Now, scientists at the U.S. Department of Energy's (DOE) Princeton Plasma Physics Laboratory (PPPL) and Princeton University's Department of Astrophysical Sciences have made a discovery that could lead to better predictions of

Studying the violent collisions of black holes and neutron stars may soon provide a new measurement of the Universe's expansion rate, helping to resolve a long-standing dispute, suggests a new simulation study led by researchers at UCL (University College London). Our two current best ways of estimating the Universe's rate of expansion - measuring the brightness and speed of pulsating and

Boasting azure waters and white sands, a Turkish lake that NASA thinks hides secrets about Mars threatens to become too popular for its own good. Lake Salda gained international renown when US scientists began poking around in preparation for the Perseverance rover mission, which has been beaming back videos from the Red Planet since February. The Jet Propulsion Laboratory even posted a

On Wednesday, April 28, 2021 at 10:50 pm local time (01:50 UTC on Thursday, April 29), a Vega launch vehicle operated by Arianespace lifted off successfully from the Guiana Space Center, Europe's Spaceport in French Guiana (South America). This mission marked Vega's return to flight, and was also the second successful launch by Arianespace's teams in less than 72 hours. The mission's prima

American astronaut Michael Collins, who piloted the Apollo 11 command module while his crewmates became the first people to walk on the Moon, died on Wednesday after battling cancer, his family said. Sometimes called "the loneliest man in history" because of his long solo flight while his colleagues loped across the lunar surface, Collins never earned the same global name recognition as Neil

Like a chameleon of the night sky, the Moon often changes its appearance. It might look larger, brighter or redder, for example, due to its phases, its position in the solar system or smoke in Earth's atmosphere. (It is not made of green cheese, however.) Another factor in its appearance is the size and shape of moon dust particles, the small rock grains that cover the moon's surface. Rese

Samples from the near-Earth asteroid (162173) Ryugu recently arrived at Earth, ready for laboratory analysis. In the meantime, ground-based measurements of Ryugu's surface are helping us to complete our picture of this nearby, rocky body. In December 2020, the Japanese spacecraft Hayabusa2 completed a daring 6-year mission, successfully landing on near-Earth asteroid Ryugu and returning a

If it touches down safely on the red planet and works as planned, the Tianwen 1 rover will be the sixth such vehicle deployed on Mars, following five predecessors launched by the United States. If the semi-autonomous craft functions efficiently, it will work for at least three months and undertake comprehensive surveys of the planet. The rover, recently named Zhurong after an ancient

Now that NASA's Ingenuity Mars Helicopter has accomplished the goal of achieving powered, controlled flight of an aircraft on the Red Planet, and with data from its most recent flight test, on April 25, the technology demonstration project has met or surpassed all of its technical objectives. The Ingenuity team now will push its performance envelope on Mars. The fourth Ingenuity flight fro
