What are gamma rays and its uses? Gamma rays are a type of electromagnetic radiation that possess high energy, high frequency, and short wavelengths. They are produced by various processes including radioactive decay, nuclear reactions, and high-energy events in space such as supernovae. Gamma rays have a multitude of uses across different fields. In medicine, […]
Looking far into space to analyze early universe timeline means peering back in time. The more distant the object, the earlier we see the Universe’s history. This is a way to see what the Universe was like shortly after the Big Bang. Einstein’s theory of relativity and Time’s slower movement Albert Einstein’s famous theory, […]
News: The ESA/JAXA BepiColombo mission project is preparing for its next close flyby of Mercury on June 19. It will be about 236 km above the planet’s surface at that time. Solar Electric Operations for BepiColombo Third’s FlyBy This is the third of six flybys that ESA’s spacecraft control team is leading BepiColombo mission through […]
Space Telescope Science Institute’s Telescope Allocation Committee outlines the target selection procedure for the next cycle of Webb observations, sparking celebration among astronomers worldwide. What is the purpose of the peer-review process? “On May 10, the Space Telescope Science Institute (STScI), NASA’s James Webb Space Telescope’s science operations center, announced the scientific program for Cycle […]
Step into a breathtaking cosmic realm as you witness the mesmerizing beauty of four composite photos capturing the cosmic wonders obtained by NASA’s Chandra X-ray Observatory and James Webb Space Telescope. You can catch a glimpse of this cosmic wonder two galaxies within these frames, a nebula, and a star cluster. Each image combines Chandra’s X-rays […]
A gamma-ray burst Gamma-Ray Burst emitted the BOAT, or “brightest of all time,” radiation pulse on October 9, 2022. This rare occurrence has piqued the interest of NASA scientists who have launched missions to study it. The burst was so powerful that it overwhelmed most gamma-ray instruments in space, making it challenging to record the […]
Have you ever gazed up at the night sky and wondered about the mysteries of the universe? From the earliest civilizations to modern-day astronomers, we have sought to understand our place in the cosmos. One of the essential tools for this endeavor is the telescope. The universe is vast and mysterious, and astronomers have been […]
When neutron stars meet, they cause Kilonova explosions, but they’re not as disruptive as you might think. A recent study indicates that when neutron stars collide, the resulting explosions are exactly spherical. This goes opposite to the current thinking that these explosions, known as kilonovas, should move in the form of flattened discs. The round […]
The X-ray vision of the NuSTAR Telescope reveals some of the most burning regions in the Sun’s atmosphere. Human eyes cannot see all of the light that our closest star emits, not even on a sunny day. The Nuclear Spectroscopic Telescope Array of NASA captures a new image that shows part of this hidden light. […]
Astronomers are getting closer to identifying sources of continuous gravitational waves. This is all thanks to analyses of Scorpius X-2, a neutron star accreting matter from a low-mass binary companion. Astronomers progress in detecting gravitational waves! So far, cosmologists have only identified gravitational waves in the form of brief bursts from black hole-neutron star mergers. […]
