There is a full universe behind that wonderful new Artemis II "Night Marble" view of Earth. Here's a breakdown of the stars (and one planet) in the field of view. Look at us! Just a planet hanging out in space. Annotation by Rodrigo González Peinado. 🧪🔭

Annotation of all the stars (and the planet Venus) visible in the background around the image of Earth in the new nighttime view of our planet from Artemis II.

Excellent piece from @astrokiwi.bsky.social @sundogplanets.mastodon.social.ap.brid.gy & Laura Revell. This one sentence is the crux of it all 👇 "There is no public mandate for a single company in one country to make changes on that scale to the planet’s atmosphere." Highly recommended. 🔭🧪

A new space race could turn our atmosphere into a ‘crematorium for satellites’

Planned ‘megaconstellations’ of satellites could cause unforeseen harm to the ozone layer and climate systems. Global regulation is needed before it’s too late.

Gordon Gauchat: Why we don’t really know what the public thinks about science. Measuring trust isn’t enough. Furthering knowledge about the institutions and norms of science is the best way to build credibility. www.nature.com/articles/d41...

A note on learning physics ⚛️ for starting PhD students: At the risk of saying something completely useless because everyone has it worked out There is no magic trick, your classmates *may* be faster than you, but they are still studying as long as they need to and you are quite capable of the same

A nice summary by @e-astronomer.bsky.social on the state of cosmology 🔭🧪. My take-aways: 1. Maybe the Universe isn’t designed to make all its secrets accessible to astronomers. 2. We always underestimate systematic errors, so shouldn’t get hung up on discrepancies. www.science.org/doi/10.1126/...

Invisible matter, invisible brains?

Cosmology finds itself in a paradoxical situation. We know everything and nothing. After years of accumulating evidence and debate, there is a consensus model about the makeup of the cosmos, known as ...

Science diplomacy is needed more now than at any time in history, given the scale of challenges the world faces. Research is often described as a form of ‘soft power’ diplomacy… The first step towards protecting science diplomacy must be to protect science itself. 🧪 www.nature.com/articles/d41...

Science diplomacy can help to heal global rifts — if research is respected

The universal language of science allows nations to reach a mutual understanding of shared problems. But that requires politicians not to meddle in how science is done.

☄️ 🔭 The impact probability of asteroid 2024 YR4 has dropped from 2.8% to 0.16%. Thanks to new observations, Earth is now at the edge of our shrinking ‘uncertainty window.’ If this trend continues, the risk may soon reach 0%.
