Juno’s star trackers weren’t meant to study dust—but they caught grains that may link Mars dust to Earth’s zodiacal light. A serendipitous find #Juno #Mars #ZodiacalLight #SpaceScience

Four silver covers sit atop COSI's detector box, shielding the flex circuits that carry detector signals to the readout electronics. In a July eighth, twenty twenty-six image, UC Berkeley engineers watch the COSI detector assembly slowly raised from a table. #COSI #SpaceScience #UCBerkeley

The Roman Space Telescope's coronagraph uses a deformable mirror — actuators push and pull the surface by microscopic amounts to cancel starlight distortion. Result: planets 100 million times fainter than their star become visible.

Next asteroid close approach: 2026 SK on 2026-Sep-19, at ~4.3 lunar distances — 1,652,398 km from Earth.

It'll speed by at 16.2 km/s. Safe but close enough to marvel.

A pulsar has been seen gathering the wind from a giant companion star.

XRISM directly observed the stellar outflow being captured by the compact object. That captured material powers strong X-ray flares.

After the recent COSPAR 46th Scientific Assembly in Italy this year, #ESAarchives looks at over 60 years of ESA-COSPAR collaboration.

COSPAR, the Committee on Space Research, was set up in October 1958 by the International Council for Scientific Unions.

NGC 2261, the Hubble Variable Nebula, is a reflection nebula lit by the star R Monocerotis. Its shifting brightness is caused by shadows from dust clouds near the star, offering a look at protoplanetary evolution. #Astronomy #Astrophysics #NASA #NGC2261 #SpaceScience

Next asteroid close approach: 2026 RG15 on 2026-Sep-15, zipping past Earth just 0.2 lunar distances away at 9.1 km/s.

That's 94,749 km — closer than many satellites!

That simple fact isn't just about astronomy.
It quietly reminds us that our own experience shapes the assumptions we carry every day. Step outside Earth's familiar rhythm, and even time begins to look different.

How do we trust data from a telescope hundreds of thousands of miles away? A new NASA project, Artifact InSPECtor, invites you to verify it. #SpaceScience sugataai.com/blog/help-re...

Never, ever look directly at the Sun through a telescope, binoculars, or your bare eyes without a certified solar filter. Doing so will cause instant, permanent blindness by cooking your retina. ☀️🙅‍♂️ #spacescience #Astronomynepal

Tom Van Flandern argues Mars anomalies, including the Cydonia Face and glassy tubes, could be testable evidence of a possible artificial past, linked to an exploded-planet hypothesis. #Mars #Cydonia #SpaceScience #Astro
