Universe
The universe is often defined as the totality of existence. The universe is everything that includes all of space, including planets, billions of galaxies, and countless numbers of stars, planets, moons, asteroids, and comets.
Even it includes time and us too. The universe is incredibly vast because it is constantly expanding. The universe also has physical laws that affect energy and matter, such as conservation laws, classical mechanics, and relativity.
Astronomers found the exact location of four fast radio bursts
Fast Radio Bursts are very mysterious bursts of radio waves, coming from all over the sky. In just a millisecond, a single burst releases...
The halo surrounding the Milky Way is much hotter than previously thought
The outer "halo" region of the Milky Way, as with other galaxies, contains the vast majority of the mass of the Galaxy. Yet the...
Classical novae are responsible for most of the lithium in our galaxy
Lithium and its compounds have several industrial applications, including heat-resistant glass and ceramics, lithium grease lubricants, batteries, and mood-altering chemicals.
However, scientists are curious to...
Determining the growth of black holes
The effects of black holes on galaxy evolution are complex and far-reaching. They are ubiquitous and span an extensive range of masses, from stellar-mass...
Astronomers captured a super-rare type of galaxy
Astronomers have seen a very curious object that they never saw before. They recently captured an image of a super-rare type of galaxy named...
ALMA detected twinkling heart of the milky way
Sgr A* sometimes flares up in millimeter wavelength. Now, for the first time, astronomers obtained high-quality data of radio-wave intensity variation of Sgr A*...
Astronomers discovered the first known Jupiter Trojan asteroid
Using the University of Hawaiʻi ‘s Asteroid Terrestrial-impact Last Alert System (ATLAS), astronomers have discovered a first-of-its-kind asteroid called Jupiter Trojan. The asteroid appears...
A massive rotating disk found in the early universe
Atacama Large Millimeter/submillimeter Array (ALMA) discovered a massive rotating disk galaxy when the universe was only ten percent of its current age, challenges the...
Why there is much more matter than antimatter in our Universe?
According to the Standard Model, matter and antimatter should have been created in equal quantities at the time of the Big Bang—yet our Universe...
Astronomers captured the birth of a pair of giant planets in PDS 70 system
Using a new infrared pyramid wavefront sensor for adaptive optics (AO) correction at W. M. Keck Observatory on Maunakea in Hawaii, a Caltech-led team...
How extraterrestrial life might evolve in alien worlds?
Humans have been wondering whether we are alone in the universe since antiquity.
We know from the geological record that life started relatively quickly, as...
Astronomers studied the emission from a bow-shock pulsar wind nebula
PSR B1929+10 is one of the nearest pulsars to Earth, with a parallax distance of about 2,057 light-years from the sun. It has a...
