Spacetime defects uncouple gravity from mass in dark matter alternative

Something seems to be missing from the universe, and the favored model of physics calls it “dark matter” – but despite a century of searching, it remains a no-show. A new paper proposes an alternative hypothesis, showing how gravity could exist without… Continue reading Spacetime defects uncouple gravity from mass in dark matter alternative

Hubble and Webb tag-team to image “Christmas Tree” galaxy cluster

The James Webb Space Telescope may have been touted as a successor to Hubble, but the old-timer still has some life left in it yet. These two iconic instruments have now teamed up to take a star-studded deep-field image of the colorful “Christmas Tree … Continue reading Hubble and Webb tag-team to image “Christmas Tree” galaxy cluster

Evidence of theorized type of black hole discovered near dawn of time

Astronomers have discovered evidence of a theorized type of black hole lurking in the distant universe. Known as an “Outsize Black Hole,” this object could help explain some fundamental cosmic mysteries, including how supermassive monsters form.Continu… Continue reading Evidence of theorized type of black hole discovered near dawn of time

“Pseudogravity” in crystals can bend light like black holes

Scientists in Japan have managed to manipulate light as though it was being influenced by gravity. By carefully distorting a photonic crystal, the team was able to invoke “pseudogravity” to bend a beam of light, which could have useful applications in … Continue reading “Pseudogravity” in crystals can bend light like black holes

Webb spots galactic smoke signals from across the universe

The James Webb Space Telescope has spotted complex organic molecules, which usually form in smoke and smog, in the very distant universe. With help from a galactic gravitational anomaly, the telescope could see the molecules from more than 12 billion l… Continue reading Webb spots galactic smoke signals from across the universe

What is gravitational lensing and how can the James Webb Telescope use it?

If you’ve seen the first images from the James Webb Space Telescope (JWST) this week (and let’s face it, how could you not?), you might have heard the term “gravitational lensing” being thrown around. But what does it mean exactly? And how can it help … Continue reading What is gravitational lensing and how can the James Webb Telescope use it?

First-ever “rogue” black hole discovered zipping through the galaxy

Astronomers believe they’ve detected the first “rogue” black hole, roaming the galaxy alone. The object made itself known when it passed in front of a background star, bending the light with its extreme gravity.Continue ReadingCategory: Space, ScienceT… Continue reading First-ever “rogue” black hole discovered zipping through the galaxy

Smallest rogue planet discovered seems to be a free-floating exo-Earth

While almost every planet we’ve ever found orbits a star of some kind, there are some loners that roam the cosmos entirely on their own. Now, astronomers have spotted the smallest of these “rogue planets” ever discovered, which is only about the size o… Continue reading Smallest rogue planet discovered seems to be a free-floating exo-Earth

Here’s a Knot of Dark Matter Binding Two Galaxies Together

Check out the first composite image of a dark matter filament in our universe. Continue reading Here’s a Knot of Dark Matter Binding Two Galaxies Together
