Nearly twice as old as the dinosaurs, horseshoe crabs have been crawling ashore for over 450 million years. Sadly, their populations have plummeted by more than 70% in recent decades. So we just announced our intent to sue the federal government for denying them #ESA protections. bit.ly/41quLDj

I disagree with those who, in the midst of the storm, are saying that ‘we all are on our own’ - It isn’t true. It can’t be true. Need proof? The Butterfly Nebula contains millions of stars and is literally ‘astronomically nextdoor’ 🙏🏽😌 #astronomy #hubble #NASA #ESA #photography #togetherness

The Butterfly Nebula from Hubble

Image Copyright: Image Credit: NASA, ESA, Hubble; Processing: William Ostling

Hubble Space Telescope

Stars can make beautiful patterns as they age -- sometimes similar to flowers or insects. NGC 6302, the Butterfly Nebula, is a notable example. Though its gaseous wingspan covers over 3 light-years and its estimated surface temperature exceeds 200,000 degrees C, the aging central star of NGC 6302, the featured planetary nebula, has become exceptionally hot, shining brightly in visible and ultraviolet light but hidden from direct view by a dense torus of dust. This sharp close-up was recorded by the Hubble Space Telescope and is processed here to show off remarkable details of the complex planetary nebula, highlighting in particular light emitted by oxygen (shown as blue), hydrogen (green), and nitrogen (red). NGC 6302 lies about 3,500 light-years away in the arachnologically correct constellation of the Scorpion (Scorpius).

Released from Hubble a few days ago - the image shows a giant among galaxies LEDA 1313424 or, the Bullseye. A smaller blue dwarf galaxy went through the centre leaving 9 star filled rings. Like dropping a pebble into a pond! Credit: #NASA, #ESA, Imad Pasha, Pieter van Dokkum 🔭 #Space #Astronomy

Rho Ophiuchi in all its beauty. The closest star forming region to our own planet at 390 light years away. Brighter stars standing out due to JWST's characteristic pattern of diffraction spikes. Image Credit: #NASA, #ESA, #CSA, STScl, Klaus Pontoppidan, Alyssa Pagan. 🔭 #Astronomy #Space

A rare and beautiful sight. The Cartwheel Galaxy, 500 million light-years away, is a stunning ring galaxy shaped by a cosmic collision. Its bright outer ring, full of new stars, expands like ripples in water. Credit: #NASA, #ESA, CSA, STScl #Space #Amazing 🔭 🧪 🎨

From attacks to the #ESA to attacks on #PublicLand, the last few weeks have been especially hard for those who care about the wild. We were made for this moment. We have risen to the occasion, countering each attack with lawsuits and advocacy. Our work has never been more important.

Only 22 #RedWolves remain in the wild. Yet these underdogs have made an incredible comeback in #NorthCarolina — the only state where they roam free — thanks to #ESA protection and investment in recovery programs. Once nearly hunted to extinction, today they're growing in numbers.

Two doomed stars created the dazzling Necklace Nebula, a cosmic ring adorned with bright gas “diamonds.” 15,000 light-years away in Sagitta, this nebula formed when one star engulfed its companion. Image Credit: #ESA, #Hubble, #NASA, K. Noll 🔭 #Astronomy #Space

A successful encounter! #ESA #BepiColombo passed Mercury today, gathering valuable science data. 🛰️🌖 Here's an image taken at 10:46 UTC (11:46 CET) 1 December, from ~51000km from the surface. x.com/BepiColombo/... Congratulations to our amazing teams for this next milestone towards Mercury orbit.

Cosmic Christmas lights! NGC 602, a star cluster in the outskirts of the small magellanic cloud. Combining X-ray from the Chandra Observatory and Infrared from JWST, we get this beautiful image. 🔭 Happy Christmas! Credit: ESA/WEBB, NASA & CSA, P. Zeidler. #Christmas #Space #NASA #ESA #SciArt

Bog #turtles are threatened more than ever since we petitioned for them. “A bog turtle can't live without its #wetlands habitat. That is what makes a bog turtle a bog turtle. It's in its name. And so if you can't protect the bog, you can't protect the turtle, right?” #NorthCarolina #ESA
After Hurricane Helene, the country’s tiniest turtle is even closer to extinction

After Hurricane Helene, the country’s tiniest turtle is even closer to extinction

These teensy tiny turtles of Appalachia barely survived a biblical flood. Inside the effort to build them a new home.
