This image shows a small part of what is called the South Polar residual cap, meaning that ice can persist well past the winter season on Mars. Due to the expansion and contraction of subsurface ice, the terrain achieves its twisted shape in areas.
“Helcaraxë” was the perilous icy wastes between the lands of Aman and Middle-earth in J.R.R. Tolkien’s “The Silmarillion”.
This is a non-narrated clip with ambient sound. Image is less than 5 km (3 mi) across and the spacecraft altitude was 245 km (153 mi). For full images including scale bars, visit the source link.

![Hubble Spots Black Hole Beam Causing Stellar Eruptions
In a surprise finding, astronomers, using NASA’s Hubble Space Telescope have discovered that the jet from a supermassive black hole at the core of M87, a huge galaxy 54 million light years away, seems to cause stars to erupt along its trajectory.
The stars, called novae, are not caught inside the jet, but in a dangerous area near it.
A nova erupts in a double-star system where an aging, swelled-up, normal star spills hydrogen onto a burned-out white dwarf companion star. When the white dwarf has collected a big enough layer of hydrogen, it explodes out into space.

![NOAA Debuts First Imagery from GOES-19
On Sept. 18, 2024, NOAA shared the first images of the Western Hemisphere from its GOES-19 satellite. The satellite’s Advanced Baseline Imager (ABI) instrument recently captured stunning views of Earth.
GOES-19, NOAA’s newest geostationary satellite, launched on June 25, 2024, onboard a Falcon Heavy rocket from NASA’s Kennedy Space Center. Previously known as GOES-U, the satellite was renamed GOES-19 upon reaching geostationary orbit on July 7, 2024.
The ABI, GOES-19’s primary instrument, views Earth with sixteen different channels, each measuring energy at different wavelengths along the electromagnetic spectrum to obtain information about Earth’s atmosphere, land, and ocean.
