Who are we? We find that we live on an insignificant planet of a humdrum star lost in a galaxy tucked away in some forgotten corner of a universe in which there are far more galaxies than people

NASA astronaut and Artemis II Commander Reid Wiseman took this picture of Earth from the Orion spacecraft’s window after completing the translunar injection burn. There are two auroras (top right and bottom left) and zodiacal light (bottom right) is visible as the Earth eclipses the Sun.

This and another photo of Earth are the first downlinked images from the Artemis II astronauts. See more photos from Orion as they are shared.

See and hear what the astronauts do with our 24/7 feed.

Hello, World

NASA Image of the Day - Fri, 04/03/2026 - 9:34am
This nighttime picture of Earth was taken on April 2, 2026, by an Artemis II crew member aiming a camera through a window of the Orion spacecraft. The image was captured after Orion completed its translunar injection burn, the critical maneuver that sent the spacecraft on its path toward the Moon and back.

The Habitable Worlds Observatory Will Need Astrometry To Find Life

Universe Today - Fri, 04/03/2026 - 9:10am

We’re getting closer and closer to finding a real Earth-like exoplanet. But finding one is only half the battle. To truly know if we’re looking at an Earth analog somewhere else in the galaxy, we have to directly image it too. That’s a job for the Habitable Worlds Observatory (HWO), a planned space-based telescope whose primary job is to do precisely that. But even capturing a picture and a planet and getting spectral readings of its atmospheric chemistry still isn’t enough, according to a new paper available in pre-print on arXiv by Kaz Gary of Ohio State and their co-authors. HWO will need to figure out how much a planet weighs first.

How a DIY worm farm can compost food scraps, paper or a whole kangaroo

New Scientist Space - Cosmology - Fri, 04/03/2026 - 5:00am
For those who want a little help composting, take a cue from James Woodford’s experience raising worms – both the small colony of wrigglers he keeps in a sensible bin in his city garden and the dumpster-sized worm farm he has that can turn even animal carcasses into nutrient-dense soil
