Humankind has launch more satellites in the past four years (2021 - 2025) than in the previous seven decades.

75% of the currently active satellites belong to a single operator (SpaceX).

By 2040, ~40% of the images from Hubble Space Telescope, and more than 96% from new and future space telescopes like SPHEREx, ARRAKIHS, and Xuntian will be contaminated by internet satellite constellations.

Vera C. Rubin Observatory: The Best Inventions of 2025 Find out why Vera C. Rubin Observatory is on TIME's list of 2025's best inventions.

TIME named the Rubin Observatory one of the best inventions of 2025!

"With giant mirrors concentrating starlight into a 3,200-megapixel camera, the Vera C. Rubin Observatory is expected to reveal billions of cosmic objects in the next decade."

3/ When examining plasma from individuals who received the JN.1-adapted vaccine, we observe similar levels of antibody evasion for XFG and BA.3.2. This is consistent with earlier studies.

Our recent study on BA.3.2 is now available. Thanks to Markus Hoffmann, Lu Zhang and Georg Behrens for the great collaboration. Here’s a brief summary of our findings:

SWOOSH! 🧹 When a meteoroid struck Mars, it triggered ~100 dust avalanches down an ancient volcano's slopes.

@esa.int's ExoMars Trace Gas Orbiter captured the dramatic effect of the rare cascade. A new @nature.com study examines the most common causes of these streaks.

The focus of the image is a portion of LDN 1641, an interstellar nebula in the constellation of Orion. In this view, a deep-black background is sprinkled with a multitude of dots (stars) of different sizes and shades of bright white. Across the sea of stars, a web of fuzzy tendrils and ribbons in varying shades of orange and brown rises from the bottom of the image towards the top-right like thin coils of smoke.

📷 This shimmering view from the ESA Euclid mission shows the dark cloud LDN 1641. Though nearly invisible to the human eye, Euclid’s infrared vision uncovers a rich landscape of gas, dust and dozens of newborn stars🧪🔭

A slightly blurry starfield, with a brighter white splotch in the very middle of the image. The brighter splotch is comet 3I/ATLAS.

It might not look like much, but that white blob in the middle of this image is comet 3I/ATLAS—the third known interstellar visitor ever—photographed from the orbit of Mars.

We know lots of you have been asking 3M for a Black Aura - like mask for consumer use.

Today we're excited to launch a new product to fill that hole in the market!

Introducing the headband version of BreatheTeq KN95.

Available in black and white.

A starfield with many small and colorful stars is dominated by comet Lemmon which is oriented diagonally in the frame. The comet has a greenish coma and a diffuse yellowish dust tail is pointing up from the nucleus. Layered with the dust tail is the blueish ion-tail which is much narrower and longer, stretching beyond the top of the image. The ion tail shows some slight undulations from changes in the comets activity over time.
