We've suddenly encountered a dense clustering of near Earth asteroids, getting as close as 0.1 lunar distances. This is a shared jet stream which on cosmic scales allows for elastic-free collisions and condensation. It's quite normal, and these would burn up in our atmosphere

@UAPWatchers I’m convinced that Avi Loeb just wakes up every day and tries to figure out a way to be on the news. Integrity be damned. I do agree with him on this, I just don’t think he did any actual work on it.

🚨Avi Loeb thinks that photos taken by the astronauts on the Apollo missions from the moon of UFOs likely camera artifacts In a recent interview with Tim Ventura Dr. Avi Loeb stated "to me that illustrates the fact that presumably the Apollo mission images that we see in the released files um you know the the lights in them are either uh a result of reflection from the optics within the camera. Sometimes you get those flashes of light from impact of of rocks on the surface of the moon that somehow shattered the moon's surface." #ufotwitter #uapX #UAPFILES Source: youtube.com/watch?v=iUMbxA…

Spiralling global temperatures (1850-2026) It is exactly 10 years since I first put this animated graphic of changes in global temperature online. #ClimateSpiral It instantly went viral. People watched it over and over again. It still offers the power to shock a decade on.

A rocket booster will slam into the Moon on August 5. 2025-010D is the upper stage of a Falcon 9 rocket that brought the Blue Ghost Mission 1 to the Moon.

Ever seen a piece of 1960s space hardware still haunting Earth's neighborhood decades later? 🚀 This NASA JPL animation shows J002E3 - the spent S-IVB third stage from Apollo 12's Saturn V (launched November 1969). In 2002, amateur astronomer Bill Yeung spotted it and logged it as a near-Earth asteroid. Turned out to be a 33-year-old rocket stage. Watch the cyan path trace its journey from May 23, 2002 to June 17, 2003. It drifts in from the left, loops and twists around Earth and the Moon in wild, non-repeating arcs, threading past the L1 point - the gravitational gateway between Earth's and the Sun's sphere of influence - while the Moon tugs it back and forth in a chaotic, unpredictable dance. No neat ellipses. No tidy repeating orbits. Just a 50-year-old rocket stage being slowly torn between three gravitational masters. No trajectory predictor in 1969 could have told you where this thing would be in 2002. Chaos saw to that. 🧵 Part 2: the full orbital mechanics breakdown ↓

@StefanBurnsGeo The Planetary Society has independently reviewed the radar evidence from 2021 and publicly confirmed there is no impact risk. Just in case that gives you any peace of mind.

@RichardFaulkne3 @earthcurated Radio telescopes are not useful unless the pointing is very precise. Looking for long-period comets with such a device is probably a worthless endeavor. Discovering a new meteor shower is a better way to predict a possible coming of a long-period comet.

@earthcurated Long-period comets 🦕 🦖 💫 We need a 1 kilometre wide radio telescope, which can be built into a crater, similar to the Arecibo dish 📡 on the lunar far side, to detect these threats to Earth way soon, to be able to alter their trajectory in ample time🙏🏻🌍🖖🏻 Radio quiet zone

Captured this with my telescope in 30 minutes last night from my back yard in Los Angeles using the Unistellar EVscope . This supernova is in a galaxy 50 million light years away. So the light you’re seeing is from 50 million years ago!

Happy 36th Anniversary to the greatest telescope of all time! Here is a Jupiter image i processed from the HST raw data archive some time back. It shows Jupiter with two of its moons, Ganymede (left) and Io (right.) You can see some of the volcanic spots on Io, while Ganymede's icy surface shows plenty of detail. The image is near to true colour but not perfect as a near UV filter was used for the B channel which skews contrasts/colour somewhat. There is a vast amount of raw data from the scope available in the archives, a good amount of which has never been processed for public release - worth looking at for those interested in processing data sets from Hubble. #HubbleSpaceTelescope

@drew4worldruler It is not uncommon for comet estimates to vary by 2-3 magnitudes on a given day. Different telescopes, software, elevation in the sky, seeing conditions, etc.

🔭 HUBBLE OBSERVES 3I/ATLAS ANOMALY The Hubble telescope observed 3I/ATLAS recently on April 10th and found that it is far brighter than predicted by JPL54 and seems to be more active than stands to reason at this distance from the Sun. The data was processed and released just minutes ago by astronomer Toni Scarmato. Observing it at this distance is obviously quite difficult and he commented that the short exposure time creates a low signal-to-noise ratio which muddies the waters somewhat. All that said, if this data is confirmed to be correct, this level of activity at a distance of nearly 1 billion kilometers from the Sun would be a true anomaly. Stay curious. 📸 Toni Scarmato #3IATLAS #3IATLAScomet #Comet
