Welcome to the Daily Telescope. There is a little too much darkness in this world and not enough light, a little too much pseudoscience and not enough science. We'll let other publications offer you a daily horoscope. At Ars Technica, we're going to take a different route, finding inspiration from very real images of a universe that is filled with stars and wonder.

Good morning. It's June 1, and today's photo comes from the James Webb Space Telescope. It's a banger.

This telescope, launched 18 months ago now, had as one of its express goals to deliver insights about the early Universe. The most straightforward way of doing so is to collect the faintest, most distant light that has spent the longest time traveling to reach Earth.

Welcome to the Daily Telescope. There is a little too much darkness in this world and not enough light, a little too much pseudoscience and not enough science. We'll let other publications offer you a daily horoscope. At Ars Technica, we're going to take a different route, finding inspiration from very real images of a universe that is filled with stars and wonder.

Good morning. It's May 29, and today's photo comes from NASA's Mars Reconnaissance Orbiter, which is, you guessed it, in orbit around Mars.

The image shows an area of sand dunes on Mars in the springtime, when carbon dioxide frost is sublimating into the air. According to NASA, the pattern of dark spots is due to the fact that the sublimation process is not uniform.

At Ars Technica, we're going to take a different route, finding inspiration from very real images of a universe that is filled with stars and wonder.

Good morning. It's May 24, and today's photo comes from the European Space Agency's new Euclid space telescope.

Launched in July 2023, the mission is intended to create a giant map of the Universe, across more than one-third of the nighttime sky. Its big-ticket goal is to help scientists better understand the nature of dark matter and dark energy, which account for the vast majority of the mass in the Universeβ€”but about which we know almost nothing.
