Gas cloud collisions during galaxy mergers compress interstellar material, triggering new star formation, as observed in interacting systems studied by NASA and reported by Universe Today.

The James Webb Space Telescope has captured a remarkably intimate portrait of two small galaxies locked in a slow, spiraling ...

A physicist has proposed a bold experiment that could allow gravitational waves to be manipulated using laser light. By ...

Gravity used to be the most down-to-earth of ideas, the thing that kept apples falling and planets in line. Now a growing ...

Sometimes the universe is just too complicated to analyze. Heck, if you take a tennis ball and toss it across the room, even that is practically too complicated. After it leaves your hand, the ball ...

Astronomers have confirmed the existence of a “rogue planet”, a world about the size of Saturn, that is wandering through ...

Gravity is a ubiquitous part of our daily lives — whether we’re being tragically brought to our knees after tripping on the rug or gleefully jumping from a swing’s apex. But despite how common the ...

In what appears to be a masterful illusion, astronomers at Gemini Observatory have imaged two nearly identical spiral galaxies in Virgo, 90 million light years distant, in the early stages of a gentle ...

The study of gravitational dynamics interweaves the classical and quantum realisations of gravity, employing both traditional methods and modern amplitude techniques. At its core, the subject ...

It's fun to think about how we know stuff. For instance, the sun has a mass of about 2 x 10 30 kilograms. That is such an enormous mass that it's difficult to comprehend. And if it's so difficult for ...
