75% of US scientists who answered Nature poll consider leaving
More than 1,600 readers answered our poll; many said they were looking for jobs in Europe and Canada.Witze, Alexandra
Wow – didn’t think I’d be in tears today, but this message sent home from Gaia as it was shut down forever today hits hard 😭
What you’re seeing is a map of the 106 CCD detectors that Gaia used to measure the positions of billions of stars in the Milky Way for the past 11 years 🛰️✨
They were turned off in a special sequence … 😕

Messier 81
apod.nasa.gov/apod/image/2503/…
One of the brightest galaxies in planet Earth's sky is similar in size to our Milky Way Galaxy: big, beautiful Messier 81. Also known as NGC 3031 or Bode's galaxy for its 18th century discoverer, this grand spiral can be found toward the northern constellation of Ursa Major, the Great Bear. The sharp, detailed telescopic view reveals M81's bright yellow nucleus, blue spiral arms, pinkish starforming regions, and sweeping cosmic dust lanes. But some dust lanes actually run through the galactic disk (left of center), contrary to other prominent spiral features. The errant dust lanes may be the lingering result of a close encounter between M81 and the nearby galaxy M82 lurking outside of this frame. Scrutiny of variable stars in M81 has yielded a well-determined distance for an external galaxy -- 11.8 million light-years.

🧵 4/5
This graphic from the WMO report is one of the best visuals I have seen that clearly illustrates the connection between increasing greenhouse gas concentrations, rising temperatures, and reinforcing feedback loops that lead to devastating high-impact events with consequent risks to populations around the world.
It's not a pretty picture.

State of the Global Climate 2024
The global climate system is complex. In order to unpack such complexity, the WMO State of the Global Climate uses seven Climate Indicators to describe the changing climate.Esri
If you do NOT want to be one of the many who remain blissfully uninformed — those who somehow can stay complacent amid increasing climate chaos — here is an excellent resource for learning what you need to know.
The World Meteorological Organization (WMO), an agency of the United Nations, provides an annual report on the state of the global climate. This year's effort includes a helpful explainer that covers all the basics with a few minutes reading.
SEE THE EXPLAINER ➡️ storymaps.arcgis.com/stories/4…
I'm going to pick out several highlights and discuss them in a thread below. This post will serve as an introduction. 🧵 1/5

We live in interesting times. Friend of mine is a scientist in France. He just got briefing on what to do when traveling to the US. He was told to use an empty, freshly installed laptop with nothing but his presentation on it. Uninstall all messengers and social media. If he has to surrender any of his devices even for a minute, he shall get it checked by the French secret service for back-doors and Trojans.
I guess I rather stay home than going to a conference in the US.

Desert Geology, Desert X 2025, Coachella Valley, California
Desert X is produced by The Desert Biennial, a not-for-profit 501(c)(3) charitable organization founded in California, conceived to produce recurring international contemporary art exhibitions that activate desert locations through site-specific installations by acclaimed international artists. Its guiding purposes and principles include presenting public exhibitions of art that respond meaningfully to the conditions of desert locations, the environment and Indigenous communities; promoting cultural exchange and education programs that foster dialogue and understanding among cultures and communities about shared artistic, historical, and societal issues; and providing an accessible platform for artists from around the world to address ecological, cultural, spiritual, and other existential themes.

Ancient Ogunquit Beach on Mars
apod.nasa.gov/apod/image/2503/…
This was once a beach -- on ancient Mars. The featured 360-degree panorama, horizontally compressed, was taken in 2017 by the robotic Curiosity rover that explored the red planet. Named Ogunquit Beach after its terrestrial counterpart, evidence shows that at times long ago the area was underwater, while at other times it was at the edge of an ancient lake. The light peak in the central background is the top of Mount Sharp, the central feature in Gale Crater where Curiosity explored. Portions of the dark sands in the foreground were scooped up for analysis. The light colored bedrock is composed of sediment that likely settled at the bottom of the now-dried lakebed. The featured panorama (interactive version here) was created from over 100 images and seemingly signed by the rover on the lower left.

SuperCam Target on Ma'az
apod.nasa.gov/apod/image/2503/…
What's the sound of one laser zapping? There's no need to consult a Zen master to find out, just listen to the first acoustic recording of laser shots on Mars. On Mars Rover Perseverance mission sol 12 (March 2, 2021) the SuperCam instrument atop the rover's mast zapped a rock dubbed Ma'az 30 times from a range of about 3.1 meters. Its microphone recorded the soft staccato popping sounds of the rapid series of SuperCam laser zaps. Shockwaves created in the thin Martian atmosphere as bits of rock are vaporized by the laser shots make the popping sounds, sounds that offer clues to the physical structure of the target. This SuperCam close-up of the Ma'az target region is 6 centimeters (2.3 inches) across. Ma'az means Mars in the Navajo language.
