Nearly 49 years after its launch, Voyager 1 is about to achieve a historic first: the only human-made object ever to cross the one-light-day mark—roughly 16 billion miles from Earth—pushing humanity’s reach into the true depths of interstellar space.

Pspspsp! Just in time for Halloween, NASA’s Hubble and James Webb Space Telescopes recently stared at an eerie star-forming scene within the Carina Nebula, a massive gas and dust cloud located approximately 7,500 light-years away from Earth.

🆕 Just in time for Halloween, a ghostly nebula lurks within sight of @Hubble_Space and the NASA/ESA/CSA James Webb Space Telescope
This is the Cat’s Head Nebula 🐱 a star-forming region located approximately 7,500 light-years from Earth. It is named for its resemblance to a cat sitting with its back towards Earth, its ‘head’ turned to the side. 1/4
ALT A collage of three images of the Cat’s Head Nebula. On the right is a Hubble visible-light image. A dark brown, opaque filament of dust is in the center, stretching from the bottom to almost the very top. It has a narrow, irregular shape that resembles a cat sitting with its back toward the viewer and a tail extending downward. In the centre is Webb’s NIRCam view where bright red spot marks the eye. The top half of the background is bright blue. Approximately halfway down, cutting diagonally across the frame, the background colour changes from blue to yellow, orange, and finally red near the bottom. On the right is Webb’s MIRI view. A bluish-gray filament of dust is in the center, stretching from the bottom to almost the very top. It has a narrow, irregular shape that resembles a cat sitting with its back toward the viewer and a tail extending downward.

Artemis III will be one of the most complex test missions in NASA history.
Launching in 2027, Artemis III astronauts will practice rendezvous and docking with two commercial lunar landers designed to carry crew from the Orion spacecraft to the lunar surface.
Details below ⬇️

The core stage of the rocket is a burnt orange color. It is topped with the white Orion spacecraft and sandwiched between two white solid rocket boosters. The mobile launcher is a trussed structure that stands behind the rocket. The perspective of the image if from below the rocket looking upward. Credit: NASA/Brandon Hancock

NEWS: Starship Flight 15 eyes November 8 with a dual catch, and Flight 16 could launch from Florida 🚀🚀
Starship could pull off two firsts before the year is out. Flight 15 is now eyeing November 8 with an attempt to catch both the Super Heavy booster and the Ship, and Flight 16 could become the first Starship launch from Florida's Launch Complex 39A in December.
A dual catch means the whole rocket comes home ready to fly again, which is the entire point of Starship. A second launch site on the East Coast matters just as much, because it ends the reliance on a single pad in Texas. If both happen, Starship ends 2026 looking like an operational system rather than a test program.

The Nancy Grace Roman Space Telescope has been named one of TIME's Best Inventions of 2026.
Roman continues its journey in space to its final orbit, completing critical milestones along the way. We expect first images by early 2027.

Launching on 19 October, @JAXA_en's Martian Moons eXploration (MMX) mission will attempt a world-first sample return from Mars’s moon Phobos. We're contributing deep-space communication technology and ground station support to help make the mission possible.

There is no fixed distance to Mars. Sometimes it is almost next door. Sometimes it is nearly seven times farther.
Earth and the Red Planet race around the Sun at different speeds, so the gap between them never stays still. At the closest approach, during opposition, only 55.76 million km separate us. At the farthest point the gap stretches to 401 million km. That is why missions do not leave whenever they feel like it: they wait for a narrow launch window, so they do not burn extra fuel or spend longer in space than they have to.

This is the most exciting time at NASA since the Kennedy era.
@POTUS has given us the mission: return to the Moon, build the Moon Base, pioneer nuclear spaceflight, advance extraordinary science, and win the new space race.
It was great to see so many of those builders, scientists, and technologists recognized at the Golden Age of Science summit this week.

Happy 200,000 orbits to Hubble! 🥳
Hubble completed its 200,000th orbit around Earth on 19 September 2026. On that day, it completed an observation pertaining to one of its scientific legacies: measuring the expansion rate of the Universe.
This observation involved the galaxy cluster MACS J0417 (left-centre of this image). 1/2
