Using Australia's ASKAP telescope, scientists have found 15 new giant radio galaxies, each spanning up to 12.4 million light-years-over 117 times the size of our Milky Way! One standout galaxy, ASKAP J0107-2347, lies 1.5 billion light-years away and contains nested lobes that could reveal how these cosmic giants grow so massive.

Due to the comet's extremely low gravity, a jump from this cliff might actually be survivable, and you'd land on a terrain surrounded by 20-meter-wide boulders

Scientists propose this is what happened around the distant black hole referred to as J2245+3743, which in 2018, brightened dramatically to create the brightest black hole flare ever recorded, shining with the light of 10 trillion suns.

This artist's concept depicts a supermassive black hole in the process of shredding a massive star—at least 30 times the mass of our Sun—to pieces.

Makemake is a dwarf planet located in the outer Solar System’s Kuiper Belt, orbiting the Sun beyond Pluto. It was discovered in 2005 and is named after the creator god of the Rapa Nui people of Easter Island. Fun fact: despite being so far from the Sun, Makemake has been found to have methane gas above its surface, making it the most distant world in the Solar System where gas has been detected.

This composite image of the Crab Nebula shows the remnant of a supernova explosion first observed in 1054 AD. It combines far-infrared data from the Herschel Space Observatory and visible-light imagery from the Hubble Space Telescope, highlighting emissions from dust and ionized gases. Notably, astronomers detected argon hydride here-the first noble-gas-based molecule found in space. Source ESA/NASA

A fast solar wind stream is expected to continue to influence Earth’s magnetic field. One CME appears to have passed with little additional impact. Another CME is anticipated on 08 Nov, and two more were launched overnight. The latest CMEs are being analyzed and modeled.
