Hera will perform a swingby of Mars in March 2025 as a way of gathering extra momentum on its way to the Didymos binary asteroid system. The spacecraft will fly within the orbits of both Martian moons Deimos and Phobos, and perform science observations of the former body and the planet's surface, in synergy with the UAE's Hope orbiter and gathering preparatory data for JAXA-DLR's MMX Martian Moons eXploration mission due to be launched in 2026.

How the 47-year-old Voyager spacecraft are still exploring space

The gruesome palette of these galaxies is owed to a mix of mid-infrared light from the NASA/ESA/CSA James Webb Space Telescope, and visible and ultraviolet light from the NASA/ESA Hubble Space Telescope. The pair grazed one another millions of years ago. The smaller spiral on the left, catalogued as IC 2163, passed behind NGC 2207, the larger spiral galaxy at right. Both have increased star formation rates. Combined, they are estimated to form the equivalent of two dozen new stars that are the size of the Sun annually. Our Milky Way galaxy forms the equivalent of two or three new Sun-like stars per year. Both galaxies have hosted seven known supernovae, each of which may have cleared space in their arms, rearranging gas and dust that later cooled, and allowed many new stars to form. (Find these areas by looking for the bluest regions).

Creepy cosmic eyes stare out from space in Webb and Hubble image

Fittingly nicknamed the Dark Wolf Nebula, this cosmic cloud was captured in a 283-million-pixel image by the VLT Survey Telescope (VST) at ESO’s Paranal Observatory in Chile. Located around 5300 light-years from Earth, the cold clouds of cosmic dust create the illusion of a wolf-like silhouette against a colourful backdrop of glowing gas clouds.

This artist’s concept depicts a potential volcanic moon between the exoplanet WASP-49 b, left, and its parent star. New evidence indicating that a massive sodium cloud observed near WASP-49 b is produced by neither the planet nor the star has prompted researchers to ask if its origin could be an exomoon.

Scientists have not yet found direct evidence of a moon outside our solar system -- but they just found a hint of a hellish one.

This image shows an area of the mosaic released by ESA’s Euclid space telescope on 15 October 2024. The area is zoomed in 150 times compared to the large mosaic. On the left of the image, Euclid captured two galaxies (called ESO 364-G035 and G036) interacting with each other, 420 million light-years from us. On the right of the image, galaxy cluster Abell 3381 is visible, 678 million light-years away from us.

The huge and detailed mosaic is just a preview of the data to come from this recently launched space telescope.
NASA astronaut Matthew Dominick captured this timelapse photo of Comet C/2023 A3 (Tsuchinshan-ATLAS) from the International Space Station as it orbited 272 miles above the South Pacific Ocean southeast of New Zealand just before sunrise on Sept. 28, 2024. At the time, the comet was about 44 million miles away from Earth.
