If there are multiple universes, which of them are capable of harboring life and why? A physicist comes up with a number, and that number is the difference between the number of baryons and antibaryons in the universe. Find out what the heck this means by reading more!
Our Sun is the nearest star to us. We have worshipped it, bathed in its light, and, of course, studied it. Scientists regularly use our Sun as a model for how similar stars should work. Thus, scientists develop the theory READ MORE
Our ability to use mathematics to describe and manipulate the natural world may not be an anomaly or trick, but instead could be a natural aspect of the structure of physical reality.
Jacob Haqq-Misra, Ravi Kopparapu, and Eric Wolf attempt to address this question in a recent paper titled “Why do we find ourselves around a yellow star instead of a red star?” and published in International Journal of Astrobiology.
A Coronal Mass Ejection means that the corona, a layer of the sun, explodes, ejecting particles into space. Supernova cosmic rays or interstellar clouds could be the possible scenarios for strong radiation.
Radio astronomers working with a radio dish telescope detected something a bit unusual. They were seeing a very fast radio burst, faster and more irregular than any signal in the history of radio astronomy. This radio burst was coming at very short time scales, lasting just a few milliseconds. The signal was irregular, very fast, and strong. This rapid burst has been something of a mystery since it was first discovered.
Large stars and planets in space have intense gravity. The gravity of these large celestial bodies is so strong, that they actually warp the empty space around them. Also, in space, time progresses differently when near celestial bodies. Because of READ MORE
Our understanding of astrophysics states that we should be seeing co-orbiting planets when astronomers look through their telescopes. Co-orbiting planets are planets of roughly similar size that have overlapping orbits around their host star. These two planets orbit so closely READ MORE
At the center of the Milky Way Galaxy, there is a supermassive black hole. This is normal — at the center of almost every galaxy there is a black hole that is millions or billions times heavier than our sun. READ MORE
Using an experiment carried into space on a NASA suborbital rocket, astronomers at Caltech and their colleagues have detected a diffuse cosmic glow that appears to represent more light than that produced by known galaxies in the universe. The researchers, READ MORE
