Binary Star System D9 Found Orbiting Sagittarius A* Near Milky Way’s Core
Astronomers have detected a young binary star system, D9, orbiting Sagittarius A*, the supermassive black hole at the Milky Way's centre. This challenges previous assumptions about star survival near intense gravitational forces. The discovery was made using the European Southern Observatory's Very Large Telescope. Future research with advanced tel...

Hubble Captures NGC 5643’s Spiral Arms, Star Formation, and Hidden Black Hole
The NASA/ESA Hubble Space Telescope has captured detailed images of the spiral galaxy NGC 5643, located 40 million light-years away. This grand design galaxy features striking spiral arms outlined by young blue stars and dust clouds, with star-forming regions visible as pinkish hues. Ultraviolet and X-ray studies have revealed an active galactic nu...

Scientists Predict Ultramassive Black Holes Can’t Grow Beyond 100 Billion Suns
Scientists led by Dr Priyamvada Natarajan from Yale University have discovered that ultramassive black holes likely cannot exceed 100 billion solar masses. These giants regulate their own growth by emitting gas jets that heat and expel surrounding material, cutting off their gas supply. Additionally, the team is exploring intermediate-mass black ho...

James Webb Telescope Breaks Record with Discovery of Early Galaxies Dating 200 Million Years After Big Bang
The James Webb Space Telescope has spotted five galaxy candidates dating back to 200 million years after the Big Bang. These findings could transform our understanding of early cosmic evolution. Discovered via gravitational lensing, these galaxies, if confirmed, predate known formations and offer vital insights into the universe’s infancy. Scient...

James Webb Space Telescope Reveals That Supermassive Black Holes Might Have Been Created Right After Big Bang
The James Webb Space Telescope has detected massive black holes from the early universe, just millions of years post-Big Bang. A new hypothesis suggests they could have formed from primordial “seeds” during the chaotic initial moments of the universe, bypassing the need for stellar collapse. This idea challenges traditional theories and may res...

NASA's Swift Observatory Discovers Twin Black Holes Disturbing Galactic Gas Clouds
NASA's Swift Observatory has recorded a unique signal from two orbiting black holes interacting with a gas cloud in a distant galaxy. This phenomenon, called AT 2021hdr, is marked by recurring gas disturbances due to the black holes' orbit, which astronomers believe could eventually lead to their merger. Observations continue, promising insights in...

NASA’s Chandra Telescope Observes Mysterious 'Knots' Blasting from Nearby Black Hole Jets
NASA’s Chandra X-ray Observatory has unveiled mysterious "knots" in the jet of a supermassive black hole in Centaurus A, a nearby galaxy. These bright, fast-moving features exhibit a higher speed in X-rays than in radio wavelengths, hinting at unexplored physics in black hole jets. Despite financial uncertainties surrounding Chandra's operations,...

Astronomers Identify Black Hole Consuming Matter 40 Times Its Theoretical Limit
Astronomers using NASA's James Webb Space Telescope have discovered LID-568, a black hole that is consuming matter at a rate over 40 times the theoretical Eddington limit. This discovery, made in a galaxy formed only 1.5 billion years after the Big Bang, sheds light on how supermassive black holes might have evolved rapidly in the early universe. R...

Two Black Holes With Unusual Behaviour Disrupt Traditional Theories About Their Formation
Astronomers are observing two unique black holes defying established cosmic theories. One, known as the "serial killer" black hole, is preparing to consume its second star in five years, an event that rarely occurs within such a timeframe. The other black hole, part of a triple system called V404 Cygni, has a structure that defies traditional black...

JWST Spots Isolated Supermassive Black Hole-Powered Quasars in the Early Universe
A team using the James Webb Space Telescope has discovered supermassive black hole-powered quasars in unexpectedly isolated environments. These lonely quasars, some of the earliest in the universe, present a mystery as they lack the dense surroundings that current theories suggest are needed for black hole growth. This discovery is pushing scientis...

NASA Selects Two Astrophysics Mission Proposals for X-Ray and Far-Infrared Wavelength Observations
NASA has selected two mission proposals for further study, focusing on X-ray and far-infrared wavelengths to explore key cosmic phenomena. The Advanced X-ray Imaging Satellite, led by Christopher Reynolds, will investigate supermassive black holes and galaxy evolution. The Probe Far-Infrared Mission, led by Jason Glenn, will examine planetary forma...

Supermassive Black Hole Jets Spark Increased Nova Explosions, Hubble Discovers
Recent findings from the Hubble Space Telescope reveal that supermassive black hole jets may be responsible for an increase in nova explosions in nearby double-star systems. This unexpected connection indicates that the energetic jets emitted by black holes can influence the surrounding stellar environment, leading to heightened activity in nova er...

Japan’s XRISM Telescope Delivers Insights from a Supermassive Black Hole and a Supernova
Less than a year since Japan's X-Ray Imaging and Spectroscopy Mission (XRISM) launched, it has delivered its first results, uncovering crucial information about black holes and supernova remnants. XRISM is a collaborative effort between the Japan Aerospace Exploration Agency (JAXA) and the European Space Agency (ESA). Its observations have revealed...
