#Astronomers Uncover Possibly the Largest #BlackHole: It ‘Bends Light Into a Giant #EinsteinRing’ - Good News Network

ground.news/article/giant-blac

Ground News · Astronomers Uncover Possibly the Largest Black Hole: It ‘Bends Light Into a Giant Einstein Ring’ - Good News NetworkIt may be the most massive black hole ever found. 36 billion times larger than the mass of our Sun, it was previously hidden from astronomers while existing at the heart of the Cosmic Horseshoe galaxy, previously photographed by space telescopes. The giant space phenomenon bends light into a perfect Einstein ring and “whips nearby […] The post Astronomers Uncover Possibly the Largest Black Hole: It ‘Bends Light into a Giant Einstein Ring’ appear…

Uncovering the cosmic dawn from the far side of the #Moon
#Astronomers are planning to launch a tiny #spacecraft to the far side of the Moon to listen out for "ancient whispers" in a quest to uncover the secrets of the early universe. The mission will focus on understanding the 'Cosmic Dawn', a period in the early stages of the universe after the #BigBang but before the first #stars and #galaxies appeared.

New Research Bolsters Freaky Theory That #Earth Sits in a Giant Cosmic Void
This theory could finally solve one of the biggest mysteries in #cosmology.
The fact is, #space is likely peppered with bubbles of relative emptiness, and some #astronomers believe we’re sitting inside of one. A growing body of evidence suggests that our entire #MilkyWay #galaxy is located within an enormous cosmic void.

#MilkyWay galaxy might not collide with #Andromeda after all
#Astronomers ran 100,000 computer simulations using combined Hubble/Gaia #space #telescope data.
Both the Milky Way and the Andromeda galaxies (M31) are part of what's known as the Local Group (LG), which also hosts other smaller galaxies (some not yet discovered) as well as dark matter. Both already have remnants of past mergers and interactions with other galaxies, according to the authors.

#JWST peers through dusty curtain to catch young #star making baby #planets
Observations of #HOPS315 align with theories of how our own #solarsystem began to take shape
"This is the first time that #astronomers have been able to see details of the inner structure of such a system. This provides an opportunity to study how planetary systems such as ours were shaped in the first stages of their existence."

Based on the current understanding of the #SolarSystem and the @VRubinObs #telescope’s 🔭 planned observing schedule, an international team of #astronomers predicts that #Rubin’s bounty will include 89,000 📊 new near-Earth #asteroids ☄️, 3.7 million new main-belt asteroids, 1,200 new Centaurs and 32,000 new objects beyond #Neptune nytimes.com/2025/06/23/science

Much smaller than gas-giants and typically cooler than hot Jupiters, sub-Neptunes were extremely challenging to observe before the launch of #JWST.

Though they appear to be the most common type of #exoplanet in our galaxy, you won’t find them in our solar system.

Astronomers are trying to understand how these planets formed and evolved, why they are so common, and why they don’t orbit our Sun.
