Snack time! 🍴 Hubble spotted a burned-out star eating a Pluto-like object. This "snack" is an object from the star system’s own version of the Kuiper Belt, which is an icy ring of debris that encircles our solar system:

NASA unveiled close-up pictures of the interstellar comet known as 3I/Atlas that’s making a quick tour of the solar system. Discovered over the summer, the comet is only the third confirmed object to visit our corner of the cosmos from another star.

sky: guesses the word nani: gives hints 🐱: this is an object 🐶: krub 🐱: it's an object that people must give when they are proposing 🐶: an engagement ring! a wedding ring! 🐱: but this time, the ring is really expensive 🐶: diamond ring... 20-carat! 🐱: (diamond ring is) correct~ 🐶: 😁 #SkyNaniSToTheNFancon #สกายนานิ #skynani

Hubble and the Keck Observatory studied what's likely a three-body system of icy space rocks in the Kuiper Belt, beyond Neptune. If confirmed, this finding suggests that there could be similar triples waiting to be discovered:

Hubble spotted an unusual star 128 light-years away. With its unique ultraviolet capabilities, Hubble determined this star is a rare ultramassive white dwarf, made up of merged stars: Find out more about this star's intriguing atmosphere in this video ⬇️

41P likely originated in the Kuiper Belt, a collection of icy bodies beyond Neptune's orbit. The comet was then flung into its current trajectory by Jupiter’s gravity, now visiting our inner solar system every 5.4 years. Find out more:

In a historical milestone, Hubble has spotted asteroids colliding ☄️ at the nearby star Fomalhaut. In 2008, scientists used Hubble to discover a candidate planet around Fomalhaut, an object called Fomalhaut b. While searching for Fomalhaut b in recent Hubble observations, scientists discovered it was actually a dust cloud masquerading as a planet – the result of colliding planetesimals. They were also surprised to find a second dust cloud! They had just witnessed a collision between massive objects. The Fomalhaut system seems to be in dynamical upheaval – a similar state to our own solar system in the first few hundred million years after formation.

🚨 BREAKING: Harvard astrophysicist Avi Loeb says a mysterious interstellar object may be carrying traces of alien life. Scientists detected methane around 3I/ATLAS — a giant object from another star system racing through our Solar System. 👽 Could microbes be hidden inside its icy core? 🧬 Could it be carrying the remnants of an extinct alien civilization? 🌌 Researchers are even exploring whether advanced beings could have used objects like this to spread life across the Milky Way. The most shocking part? Experts now say evidence of extraterrestrial technology may not arrive in a signal... It may already be here. #Aliens #UFO #UAP #Space #Astronomy #Disclosure

Across a dying star 💀⭐ The Cat’s Eye Nebula is a planetary nebula. This type of object appeared round (planet-like!) in early telescopes, but the NASA/ESA Hubble Space Telescope has revealed a complex morphology – this is especially true of the Cat’s Eye Nebula! In this new image, Hubble captures the core of the billowing gas, its tapestry of concentric shells, and jets of high-speed gas and dense knots sculpted by shock interactions.1/2

While watching a mammoth object the size of the C-5 take off is a feat in itself, that complex landing gear retraction system is also an attraction in itself.

Footage shows a US soldier in Afghanistan picking up an object he believes is an artillery shell, only to realize it is actually an IED. What seemed like a piece of battlefield debris became a hidden threat capable of causing severe damage. Isn’t one of the first things they get taught is not to pick up random stuff off from the ground.

A useful animation demonstrating gravitational lensing. This is when the gravity of a high mass object, like a galactic cluster, distorts the light of objects behind it. 💡 CREDIT : ESA/Hubble, L. Calçada

The angles of the jets suggest that Centaur 29P might be made of multiple objects of differing compositions that coalesced. Centaurs are like the leftovers of our solar system’s formation and in their icy bodies is preserved chemical information about our early stages.

This isn't an expanding star: this is a light echo! In this time-lapse sonification, a pulse of light from the star V838 Monocerotis gives the illusion that the surrounding dust is expanding. In reality, it's just the light from the star's flash reaching dust farther away.

A massive object is approaching our solar system behaving in ways that challenge our understanding of physics Avi Loeb says on December 19 we could capture the most detailed image of #3IATLAS a celestial Christmas surprise unlike anything seen before

Professor Avi Loeb points to 3I/ATLAS's very high speed of 130,000 mph, as an indication that it might be controlled by aliens? "It is difficult to imagine a natural process that would favor a plunge towards our inner solar system at 60 kilometers per second." "An alternative is that the object is targeting our inner solar system, by some technological design." 7 miles (15 km) in diameter. What do YOU think? First stop > Mars.

A magnet is an object that creates a magnetic field, which can attract certain metals like iron, nickel, and cobalt. This force comes from the alignment of tiny magnetic fields of atoms inside the material, making it either pull objects toward it or repel other magnets
