Lucky alignment of 2 spacecraft reveals how solar wind gets a magnetic push
Energy-packed plasma waves pump enough energy into streams of solar wind to propel them to their unexpectedly high speeds, observations by two sun-studying spacecraft suggest.
Solved: The Case of the Universe’s “Extra” Light
Astronomers may have finally solved the mystery of how dark space really is.
Explaining Different Kinds of Meteor Showers. It’s the Way the Comet Crumbles
The Universe often puts on a good show for us down here on Earth but one of the best spectacles must be a meteor shower. We see them when particles, usually the remains of comets, fall through our atmosphere and cause the atmosphere to glow. We see them as a fast moving streak of light but a new paper has suggested that the meteor showers we see can explain the sizes of the particles that originally formed the comet from where they came.
Boeing Starliner astronauts have years of medical studies helping them with longer stay in space
Starliner's astronauts will spend at least 8 months in space, longer than a typical ISS crew. But numerous other astronauts have safely spent a year on the ISS, or even longer.
Sentinel-2C launch highlights
Video: 00:14:09
The Copernicus Sentinel-2C satellite lifted off on 5 September at 03:50 CEST (4 September 22:50 local time) aboard the last Vega rocket, flight VV24, from Europe’s Spaceport in French Guiana.
Sentinel-2C joins the Copernicus family in orbit
The third Copernicus Sentinel-2 satellite launched today aboard the final Vega rocket from Europe’s Spaceport in French Guiana. Sentinel-2C will continue providing high-resolution data that is essential to Copernicus – Europe’s world leading Earth observation programme.
Dark Oxygen Could Change Our Understanding of Habitability
The discovery of dark oxygen at an abyssal plain on the ocean floor generated a lot of interest. Could this oxygen source support life in the ocean depths? And if it can, what does that mean for places like Enceladus and Europa?
Chinese astronauts study ancient microbes aboard Tiangong space station (video)
Chinese astronauts aboard the Tiangong space station are studying microbes, to help determine if some of Earth's early lifeforms can handle a simulated cosmic environment.
Hubble Telescope spies a very sparkly mini-galaxy (image)
The Hubble Space Telescope has imaged one of Andromeda's dwarf galaxies. It's named Pegasus.
Celestron Origin Intelligent Home Observatory smart telescope review
The Celestron Origin is an easy-to-use smart telescope that will have you producing stunning pictures of deep sky objects in minutes.
A Surprise Asteroid Lit Up the Sky Over the Philippines
With all of humanity’s telescopic eyes on the sky, it’s rare for an asteroid to take us by surprise. But that’s what happened this morning in the sky over the Philippines. Only hours after it was detected, it burned up in a bright flash above the island of Luzon.

Blue Origin's droneship, named "Jacklyn," arrived at Florida's Port Canaveral ahead of the inaugural launch of the company's huge New Glenn rocket next month.
Lego City Modular Space Station review
It's a little on the expensive side, but this Lego space station playset packs in multiple ways to play.
'There was some tension in the room', NASA says of decision to bring Boeing's Starliner spacecraft home without astronauts
Boeing's Starliner spacecraft will fly back to Earth for a landing on Sept. 7, but without its crew. Its two astronauts will ride home on SpaceX Crew Dragon in February 2025.
NASA clears Europa Clipper mission for Oct. 10 launch despite Jupiter radiation worries
NASA's Europa Clipper mission is on track for an October launch following tests confirming the spacecraft can handle the harsh conditions around Jupiter's intriguing moon.
A Review of Humanity’s Planned Expansion Between the Earth and the Moon
Between Low Earth Orbit (LEO) and the Moon, there is a region of space measuring 384,400 km (238,855 mi) wide known as Cislunar space. In the coming decades, multiple space agencies will send missions to this region to support the development of infrastructure that will lead to a permanent human presence on the Moon. This includes orbital and surface habitats, landing pads, surface vehicles, technologies for in-situ resource utilization (ISRU), and other elements that will enable the long-term exploration and development of the lunar surface.
A huge asteroid crash permanently altered Jupiter's biggest moon Ganymede
A colossal asteroid slammed into Jupiter's largest moon Ganymede with so much power it dramatically and permanently reoriented the moon roughly 4 billion years ago, new research suggests.
Simulating the Accretion Disk Around a Black Hole
Black holes are by their very nature, challenging to observe and difficult to spot. It’s usually observations of the accretion disk that reveal properties of the hidden black hole. There is often enough material within the accretion disk to make them shine so brightly that they can often be among the brightest objects in space. A wonderful image has been released which shows the highest resolution simulation of a black hole accretion disk ever created.
SpaceX rocket to launch new Starlink satellite fleet on Sept. 5 after delay
SpaceX will launch a new batch of its Starlink satellites into orbit on Thursday (Sept. 5) and you'll be able to watch it live online.
