Focuses on the efforts of astronomers to measure the speed of gravity. Prediction of the theory of general relativity by scientist, Albert Einstein; Interaction of gravitational waves with radio waves; Results of the astronomical study conducted by scientist,...
We’ve seen hot Jupiter exoplanets before, so that’s not particularly interesting, but after astronomers took a closer look at the planet they’ve discovered something truly bizarre: CoRoT-2b is hot in all the wrong places. When a planet is tidally locked, as CoRoT-2b is, it shows one ...
000 operational satellites in orbit around Earth, our immediate cosmic neighborhood has become busier than a big city rush hour [source:Cain]. And then there's the discarded equipment, abandoned satellites, pieces of hardware and fragments from explosions or collisions that share the skies with...
Jupiter is known as the “King of the Planets”, and for good reason. For one, it is the largest planet in the Solar System, and is actually more massive than all the other planets combined. Fittingly, it is named after the king of the Roman pantheon, the latinized version of Zeus (...
Not only is Jupiter the largest planet in our solar system, but it also spins at the fastest rate. Read More: Jupiter: Anatomy of a Gas Giant 4. True or false: Less than 3 percent of the world's population can speak four or more languages. True. Less than 3 percent of the world'...
What Is a Black Hole? Artist concept of a giant black hole: The arrows show the paths of massive objects in and around the opening of the black hole. Photo courtesy NASA Stellar mass black holes form when massive stars die. If you have read How Stars Work, then you know that ...
Researchers have identified the birth sites of massive elliptical galaxies, providing new insights into their formation which has puzzled scientists for decades. The study suggests that these galaxies were formed from large flows of cold gas and galactic collisions in the early universe, leading to ra...
Extremely hardy lifeforms have been found in such environments at the bottom of Earth’s oceans, providing clues as to how early life may have begun, and giving scientists pointers on where to look elsewhere in the Solar System:Jupiter’s moonEuropa, orSaturn’s icy moon Enceladus for example...
The most accepted hypothesis is that at the center of each of these galaxies is a massive or supermassive black hole. Around the black hole is an accretion disk of rapidly spinning gas that's surrounded by a torus (a donut-shaped disk of gas and dust). As the material from the ...
