Discovering a cosmic clock near the Milky Way's core, researchers have identified an 8.19-millisecond pulsar candidate by Sagittarius A*, offering a unique chance to test Einstein's General Relativity. This "cosmic lighthouse" provides insights into extreme gravity's effect on space-time, with groundbreaking detections from the Breakthrough Listen Galactic Center Survey.

Researchers have found a candidate millisecond pulsar near the supermassive black hole at our galaxy's center

Researchers have found a candidate millisecond pulsar near the supermassive black hole at our galaxy's center—a potential "cosmic clock" to test Einstein's theories.Deep in the chaotic center of the Milky Way lies Sagittarius A* (Sgr A*), a black hole 4 million times the mass of our sun. Finding a pulsar near this monster has been a holy grail for astronomers.

Astronomers capture a groundbreaking event as a black hole devours a white dwarf, reaching a peak luminosity of \(3 \times 10^{49}\) erg/s. Detected by the Einstein Probe, this phenomenon provides key insights into intermediate-mass black holes, with a dramatic 20-day transition from high to low-energy states. Occurring on the galaxy's remote outskirts, this tidal disruption showcases unique cosmic interactions.

It wasn't a standard gamma-ray burst. The X-ray signal appeared before the explosion, flared to immense brightness, and then vanished in just 20 days.

"Exploring the Early Universe: Rapid Formation of Galaxies Unveils Cosmic Mysteries. Just 1.4 billion years post-Big Bang, massive elliptical galaxies emerged, challenging traditional models. The infographic highlights a rapid assembly process and compares the high star formation rate and swift assembly of protocluster SPT2349-56 with our modern Milky Way."

How did massive galaxies exist just after the Big Bang?

How did massive galaxies exist just after the Big Bang? New research reveals they didn't grow slowly—they exploded into existence. For two decades, astronomers have been puzzled by a timeline problem. Massive, "old" elliptical galaxies were found existing just 1.4 billion years after the Big Bang. According to standard models, they shouldn't have had time to grow that big.

The Fermi Paradox and the Search for Cosmic Intelligence

This is the heart of the Fermi Paradox, a term for the profound conflict between the sheer statistical probability that we should be surrounded by evidence of intelligent life and the observed reality of a silent, seemingly empty cosmos. For decades, our telescopes and radio receivers have heard nothing but silence.

M dwarf stars (Red Dwarfs)

When you look up at the night sky, the stars that catch your eye are often giants—luminous, massive beacons similar to, or much larger than, our own Sun. It’s natural to think of these bright points of light as typical. But this perception is a profound illusion.

What New Scar on the Moon Teaches Us?

Despite eons of gazing at the "Man in the Moon," many of us miss the fact that our celestial neighbor is still under construction. While the massive, basin-forming impacts ended billions of years ago, the Moon is still struck by asteroids and comets today. Catching these impacts is a challenge, but thanks to the Lunar Reconnaissance Orbiter Camera (LROC), we can now spot fresh craters that appeared almost overnight.
