First week of on-sky engineering tests with the huge LSST Camera: ✅ From continuing to fine tune our complex systems and improve data quality, to successfully testing mechanical systems like the camera filter changer, we’re getting ever closer to being ready to #CaptureTheCosmos! 🔭 🧪 🧵

Mars and the Beehive Cluster through clouds. 28 April 2025. 🔭 🧪 🎨 #astrophotography #SciArt #photography #StormHour #ThePhotoHour

The world's First Look at imagery from NSF–DOE Rubin Observatory is coming in mid-2025 — and we want the whole world to join in the celebration!🥳 🔭 🧪 Help us bring Rubin to the world and join the global excitement by signing up to host a #RubinWatchParty! ➡️ rubinobservatory.org/news/host-fi...

Nature's variety never fails to surprise us. Astronomers using the #ESO #VeryLargeTelescope have found a planet in a perpendicular orbit around 2 failed stars (brown dwarfs) that orbit each other: www.eso.org/public/news/... #astronomy #astroedu #space #sciencenews #astronomynews #exoplanets #sci

The scientific return of the @vrubinobs.bsky.social is going be out of this world! Ba dum tss! Over the course of its decade-long survey, Rubin will capture every part of the Southern sky ~1000 times, in more detail than has been possible before — creating the greatest cosmic movie ever made. 🔭🧪

The space science community is deeply concerned after recent reports that NASA’s budget would be halved. buff.ly/J8Xt610 . . #astronomy #science #space #nasa #budget #astronautics #spacepolicy

𝗡𝗼, 𝗮 𝗯𝗶𝗼𝘀𝗶𝗴𝗻𝗮𝘁𝘂𝗿𝗲 𝘄𝗮𝘀 𝗻𝗼𝘁 𝗷𝘂𝘀𝘁 𝗱𝗲𝘁𝗲𝗰𝘁𝗲𝗱 𝗶𝗻 𝗞𝟮-𝟭𝟴𝗯'𝘀 𝗮𝘁𝗺𝗼𝘀𝗽𝗵𝗲𝗿𝗲. K2-18b is back in the news, now with a bold claim that biosignature molecules (DMS and/or DMDS) have been 'detected at 3σ'. Most exoplanet astronomers are extremely sceptical about these claims, let's see why (1/n). 🔭🧪🪐 #exoplanet

@drbecky.bsky.social once again does a fantastic job explaining why the reported observation of DMS in the atmosphere of K2-18b is NOT the sign of alien life the media is making it out to be. #astronomy www.youtube.com/shorts/zPYHP...

About those JWST biosignature headlines…🧪🔭

Breaking news: The U.S. Department of Energy today announced it is unilaterally cutting in half the overhead rate on its academic grants, something that a federal judge recently told the National Institutes of Health it could not do.

🧵 On 10 April 2019, the Event Horizon Telescope (EHT) team released the first-ever image of a black hole and its shadow, using radio observations of the heart of M87, a massive galaxy in the Virgo galaxy cluster Press Release (2019) ➡️ eventhorizontelescope.org/press-releas... 🔭 🧪 #cosmology

Trump FINALLY got massive crowds — just not the adoring kind. 😂✊

They are a bunch of cowards who will probably leave the room praising him and cutting another check in tribute.

New observations show that the universe’s first light penetrated the fog of the cosmic dark ages just 330 million years after the Big Bang. buff.ly/EN0emLy . . #astronomy #bigbang #cosmology #cosmicdarkages

A recent study, using data from JWST, analyzed the rotation of 263 distant galaxies, surprisingly finding that about 2/3 of them rotate clockwise, while only 1/3 rotates counterclockwise. More at my post➡️ www.tutto-scienze.org/2025/03/most... 🔭 🧪 #JWST #cosmology #universe

The Cygnus Wall, a section of the amazing North America nebula, NGC7000, in the Cygnus constellation. 1600 light years from Earth. This is about six hours worth of data shot from my Bortle 8 backyard.🔭✨ #astrophotography #astronomy #space #photography

DESI created the largest three-dimensional map of the universe ever made, using data from nearly 15 million galaxies and quasars collected in the first three years of observations. This map covers 11 billion years of cosmic history. My post: www.tutto-scienze.org/2025/03/new-... 🔭 🧪 #cosmology

New data hint that dark energy is weakening over time. If true, it means that our most trusted cosmological models may be wrong. buff.ly/SYK2u8z . . #astronomy #cosmology #darkenergy

Tonight an unbelievable **34,000 people** gathered for our Denver rally to take on billionaires and win our country back. This was the largest political gathering in Denver since Obama in 2008. Also bigger than the 2024 DNC. And the largest ever rally in Bernie’s career (and obviously, mine too).

Results by two of the most advanced cosmological surveys - the Dark Energy Spectroscopic Instrument Survey in Arizona and the Dark Energy Survey in Chile - suggest a time-varying dark energy, which, if confirmed, could lead to a fundamental shift in our understanding of the cosmos. #Cosmology 🧪

This is a very, VERY big camera. I cannot wait for this observatory to get first light. It'll be *amazing*.

“American techno-fascism is no longer a philosophical abstraction for Silicon Valley to tinker with,” chaykak.bsky.social writes. “It is a policy program whose constitutional limits are being tested right now as DOGE . . . rampages through the federal government.”

Scrub a dub 🫧 ...except no scrubbing the delicate observatory optics! We don't use cloths or lens cleaner to clean the giant camera lenses. Instead, our summit staff use a high-speed stream of carbon dioxide "snow" to push debris off of the glass surface. 🔭🧪

When you turn it on and it works spectacularly! The Rubin team has successfully completed the first on-sky engineering tests using the 144-Mpx engineering camera. Up next: installing the largest digital camera in the world, LSST Camera! 🔭🧪 rubinobservatory.org/news/rubin-completes-comcam-tests

"American statistics may have flaws of various kinds, but are generally accurate: the Billion Prices Project, tracking the online price of a billion goods in 2015 and 2016, resulted in remarkably similar readings to the official CPI." www.liberalcurrents.com/can-we-trust...

The American checks and balances system is finally waking up.

President Trump has argued that the FBI unfairly targeted him, and new bureau Deputy Director Dan Bongino has embraced and amplified that view.

The consumer confidence index recorded its biggest monthly decline since August 2021.

Caroline's Rose Cluster is a open star cluster located in the constellation Cassiopeia. Containing ~ 1000 stars it is named after Caroline Herschel who discovered it in 1783. The swirling star patterns resemble a rose. Rainy week reprocess of a photo taken last October. #astronomy #astrophotography

alert! we're organizing to help folks in astronomy + planetary sciences who've lost their jobs without warning, or have important DEIA initiatives that suddenly lost funding please share with your networks!! #extragalactic #exoplanets #astronomy #cosmology

U.S. President Donald Trump's claim that Ukraine's president is an illegitimate "dictator" aligns with Kremlin war objectives and puts Volodymyr Zelensky in an almost impossible situation, experts and analysts have told the Kyiv Independent.

The US wants to manufacture semiconductors again after Silicon Valley factory workers endured unsafe conditions, suffered miscarriages, and gave birth to children with birth defects. Subscribe to The Verge to read more from @justcalma.bsky.social: www.theverge.com/features/611...

The Kyiv Independent sat down with Gabrielius Landsbergis on the sidelines of the Munich Security Conference on Feb. 14, where the growing divergence between the U.S. and the EU on NATO and Ukraine was at the center of the discussions.

Following a loud public outcry, and relentless media campaign from outdoors enthusiasts, the Trump administration has reversed course on a plan to eliminate thousands of seasonal workers at the National Park Service.
