X-Class Solar Flare From Sunspot 3912 Causes Radio Blackouts in Southern Africa
A powerful X-class solar flare erupted from sunspot region 3912 on December 8, disrupting high-frequency radio communications in southern Africa. The flare, accompanied by a coronal mass ejection (CME), ionised Earth’s upper atmosphere, absorbing radio signals and causing blackouts in areas exposed to peak solar activity. Experts predict the CME ...

Asteroids Impacting Neutron Stars May Be the Cause of Fast Radio Bursts
Research suggests asteroid impacts on neutron stars may be the cause of mysterious fast radio bursts (FRBs). These collisions release enormous energy and match observed FRB frequency. Scientists believe interstellar objects colliding with neutron stars could account for their rate and occurrence, while repeating FRBs may stem from asteroid belts. O...

New Research Explains Zebra Pattern in Radio Waves from Crab Nebula
A new model by Mikhail Medvedev from the University of Kansas offers an explanation for the zebra-like pattern in high-frequency radio waves emitted by the Crab Pulsar. The pattern, first discovered in 2007, is likely caused by diffraction and interference of waves in the pulsar's plasma-rich environment. Medvedev’s model could also provide a met...

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,...

Sun Erupts with X2.3 Solar Flare, Causes Radio Blackouts
On November 6, 2024, sunspot AR 3883 unleashed a powerful X2.3 solar flare, causing radio blackouts in parts of South America and Africa. The flare, classified as a strong solar event, disrupted high-frequency radio signals. Scientists are awaiting data from NASA’s SOHO spacecraft to assess the potential impact of a coronal mass ejection (CME) on...

Chandra X-ray Observatory Spots Unusual Knots in Black Hole Jets
Astronomers using NASA's Chandra X-ray Observatory have found knots moving at different speeds within jets blasted by the black hole at the centre of the Centaurus A galaxy. The X-ray data revealed that these knots travel faster in X-ray wavelengths than in radio wavelengths. This discovery raises questions about how these jets work, with astronome...
