SpaceX sent 26 Starlink internet satellites to orbit from California Thursday (June 12), on the 500th overall completed mission for the company's Falcon family of rockets.

Whilst NASA funding has been slashed by the Trump administration with no allocation for Nuclear Thermal Propulsion or and Nuclear Electric Propulsion, scientists at the European Space Agency (ESA) have been studying nuclear propulsion.

Astronomers have discovered a "teenage vampire" dead star in the process of devouring a companion star during a short-lived, "missing link" phase of its evolution.

Simultaneously cooling Pluto while energizing atmospheric molecules to allow them to escape into space, Pluto's haze plays a key role in the planet's energy balance.

The “Bell test” was devised in the 1960s to uncover what’s going on in the quantum world, but it continues to be relevant today, says Karmela Padavic-Callaghan

NASA’s SLS (Space Launch System) solid rocket boosters are the largest, most powerful solid propellant boosters to ever fly. Standing 17 stories tall and burning approximately six tons of propellant every second, each booster generates 3.6 million pounds of a thrust for a total of 7.2 million pounds: more thrust than 14 four-engine jumbo commercial airliners. Together, the SLS twin boosters provide more than 75 percent of the total thrust at launch. Each booster houses eight booster separation motors which are responsible for separating the boosters from the core stage during flight.

At the top of each booster is the frustum—a truncated cone-shaped structure that, along with the nose cone, forms the aerodynamic fairing. This frustum houses four of the separation motors, while the remaining four are located at the bottom within the aft skirt.

The EPA has contradicted itself—and legal precedent—in its bid to undo Biden-era limits on power-plant climate pollution

One of the coolest designs of any star projector we've seen, we think the Dinosaur Egg Galaxy Star Projector is amongst the best options for kids.

The time-lapse footage was captured by NASA astronaut Jonny Kim.

The star cluster Pismis 24 lies within the much larger emission nebula called NGC 6357, located about 8,000 light-years from Earth. The gas below the stars glows through ionization caused by intense ultraviolet radiation from the massive young stars within the cluster.

Pismis 24, the star cluster seen here in an image released on Dec. 11, 2006, lies within the much larger emission nebula called NGC 6357, located about 8,000 light-years from Earth. The brightest object in the picture was once thought to be a single star with an incredibly large mass of 200 to 300 solar masses. That would have made it by far the most massive known star in the galaxy and would have put it considerably above the currently believed upper mass limit of about 150 solar masses for individual stars. Measurements from NASA’s Hubble Space Telescope, however, discovered that Pismis 24-1 is actually two separate stars, and, in doing so, “halved” their mass to around 100-150 solar masses each.
