NASA astronaut Christina Koch captured this incredible image from the International Space Station (ISS) yesterday. It shows a Russian Soyuz spacecraft making its way towards her, having launched from Baikonur Cosmodrome in Kazakhstan. “What it looks like from @Space_Station when your best friend achieves her lifelong dream to go to space,” Koch wrote on Twitter. “Caught the second stage in progress!”

It's a busy week at the International Space Station (ISS). With nine crewmembers currently on board, the orbiting laboratory will be unusually crowded until Thursday (Oct. 3), when three of those crewmembers are scheduled to return to Earth.

A rare trio of supermassive black holes has been caught in the act of coming together. Three of the light-gobbling monsters nuzzle shoulder to shoulder in SDSS J084905.51+111447.2, a system of three merging galaxies about 1 billion light-years from Earth, a new study reports.

The hellish planet Venus may have had a perfectly habitable environment for 2 to 3 billion years after the planet formed, suggesting life would have had ample time to emerge there, according to a new study.

Earth will soon lose a key tool in the fight to spot potentially hazardous asteroids -- and NASA has decided to fund a custom-built replacement. NASA wants to build a space telescope to survey the sky in infrared light, a much-needed boost in its program to identify and track asteroids in Earth's immediate neighborhood.

It's a pulsar, named J0740+6620, and discrepancies in the timing of its pulses has allowed its mass to be calculated to 2.14 times that of the Sun, packed into a star just 30 kilometres (19 miles) across. To put that into perspective, the Sun has a diameter of 1.391 million km (~864,000 miles).

When NASA’s new drone Dragonfly arrives on Titan, Saturn’s largest moon, it won’t roll across the surface like Curiosity, Spirit, and Opportunity have on Mars. Instead, Dragonfly is a dual-rotor quadcopter that will fly from point to point, using a vertical takeoff and landing (VTOL) system. It leverages existing drone technology we have on Earth to make the system work.

Space is hard. That was the takeaway on Sept. 7, when the Indian Space Research Organisation (ISRO) lost contact with its Vikram lunar lander during an attempt to touch down at the moon's south pole. Of the 30 soft-landing attempts made by space agencies and companies around the world, more than one-third have ended in failure...

Try as we might, we just can’t prove Einstein wrong. One prediction of his theory of general relativity is that black holes are simple objects - and listening to them “ring” indicates this is true.

For six months, NASA has been chasing big plans to land humans near the south pole of the moon in 2024. That deadline came from Vice President Mike Pence in March and represented a significant increase in speed from the human moon landing's previous timeline, targeting 2028. The project has since been dubbed the Artemis program, a nod to the fact that NASA plans to include a female astronaut in the moon landing for the first time.
