Hubble telescope snaps trippy new view of two swirling galaxies
A peculiar pair of galaxies swirls together in a mesmerizing new photo from the Hubble Space Telescope.
A new Kind of Solar Sail Could let us Explore Difficult Places to Reach in the Solar System
Solar sailing technology has been a dream of many for decades. The simple elegance of sailing on the light waves of the sun does have a dreamy aspect to it that has captured the imagination of engineers as well as writers. However, the practicalities of the amount of energy received compared to that needed to move useful payloads have brought those dreams back to reality. Now, a team led by Amber Dubill of John Hopkins University Applied Physics Laboratory and supported by the NASA Innovative Advanced Concepts (NIAC) program is developing new solar sail architecture that might have already found its killer app – heliophysics.
ESA is Developing Microbe-Killing Coatings to Make Spaceflight Healthier
Humans aren’t the only living things in place onboard the ISS. Bacteria, which has found a way to integrate itself into every biome on Earth, has also found a home in the aseptic microgravity of the space station high above it. Unfortunately, this poses a hazard to both the astronauts that live on the ISS and the station itself. But now, a team of researchers funded by ESA and the Instituto Italiano di Tecnologia (IIT) think they have a solution – make the surfaces on the ISS antimicrobial.

Reports are coming in from observers who caught a few early shooting stars.
These star-forming spirals look like galactic UFOs
The Hubble Space Telescope captured the otherworldly image of IC 564 when it looked at this region to learn more about 'clumpy' star formation.
James Webb Space Telescope will study two strange 'super-Earths'
Officials promise geology 'from 50 light-years away,' as they train the James Webb Space Telescope's high-precision spectrographs on two exoplanets.
Planets in Binary Systems Could be Habitable, But They’d Form Differently
Most of the stars in the Milky Way are single stars. But between one-third and one-half of them are binary stars. Can habitable planets form in these environments?
Want to see the potential tau Herculids meteor shower? Here's what to expect, according to NASA.
If you're hoping to see the potential tau Herculids meteor shower, NASA advises you to check the weather and be ready for the unexpected.

The first launch of the Orbex Prime ‘eco-rocket’ from a remote launch pad in the Highlands of Scotland is expected at the end of the year or in early 2023. A full-scale prototype of Prime, billed as the world’s most environmentally-friendly rocket, was unveiled to the public for the first time this month.
