A joint probe mission of ESA and Roscosmos captured a giant tree stump from the Martian surface. One of the probes on Mars recently captured a strange image on the planet’s surface.

Besides offering an incredibly cool way to get stuff into space, promises to reduce the cost of a launch by 20-fold.

The December 25 launch of the James Webb Space Telescope was a career-capping triumph for the ESA Ariane 5 rocket. The Ariane 6 cometh soon.

Astronomers at the International Centre for Radio Astronomy Research report the discovery of a repeating transient with an unusually slow spin, occurring just three times an hour. It is believed to be a new class of neutron star or white dwarf, located 4,000 light years away.

In January 1999, scientists observed mysterious motions within a solar flare.

Unlike typical flares that showed bright energy erupting outwards from the Sun, this solar flare also displayed a downward flow of motion, as if material was falling back towards the Sun. Described as “downward-moving dark voids,” astronomers wondered what exactly they were seeing.

Astronomers use fast radio bursts for the first time to measure the Hubble constant in hopes of ending the debate on the universe’s expansion rate.

There is a new speck of light in the sky right now, best observable from Earth around midnight. This blurry speck — dim as it may be, small as it may be — represents the grit and unity of thousands of people who worked together to place it in the heavens.
