The Milky Way is one of billions of galaxies in the universe and home to our own solar system. It appears as a hazy band in the sky when viewed from Earth.
The Milky Way is, in fact, the main body of our own spiral galaxy, viewed from within: binoculars or a telescope will resolve individual stars in the bright mass. The Milky Way in the Sky From Earth, without telescopic aid, the band of the Milky Way appears as a bright and hazy ...
Since Earth is situated within the Milky Way Galaxy, it is not feasible to step back and observe how the Galaxy looks when viewed from the outside. Astrometry, or the precise measurement of the motions and positions of objects, is an essential tool to gain insights into the overall ...
Now Revnivtsev and his colleagues have shown that the current feebleness of our black hole is just a passing phase. Only 350 years ago, as viewed from Earth, it was a million times brighter than it is now. Energetic X-rays The result comes from observations by Integral, ESA’s gamma-r...
Recently a new product has allowed me to take even higher quality Milky Way shots. It is astar trackercalledMove Shoot Move(MSM). This is a small, lightweight device you attach to your tripod that compensates for the earth’s movement. The allows you to take much longer Milky Way shots...
Astronomers have just discovered two dwarf galaxy candidates orbiting our galaxy. The orientation of these entities suggests there could be up to 500 similar stellar clusters circling the Milky Way, which is more than double previous estimates.
the Virgo Supercluster. The Milky Way is the second-largest galaxy in the Local Group. The milky way has at least 100 billion planets. The most known planets are in our solar system. They are in order from closest to the farest away from the sun. Mercury, Venus, Earth, Mars, Jupiter,...
The English astronomer Arthur Eddington once said, “I think there should be a law of nature to prevent a star from behaving in this absurd way!” How Microlensing Works A microlensing event occurs when a massive object, such as a black hole, passes in front of a background star. The ...
The halo of the Milky Way provides a laboratory to study the properties of the shocked hot gas that is predicted by models of galaxy formation. There is observational evidence of energy injection into the halo from past activity in the nucleus of the Milky Way1,2,3,4; however, the origin...
Here, we quantify the extent to which the activity of the supermassive black hole at the center of the Milky Way, known as Sagittarius A* (Sgr A*), may have affected the habitability of Earth-like planets in our Galaxy. We focus on the amount of atmospheric loss and on the possible ...
