Missing stars could point to alien civilizations, scientists say

by Eric Mack, c|net

Astronomers compare old views of the sky with what we see today and find that at least 100 stars appear to have vanished, or were perhaps covered up.

On March 16, 1950, astronomers at the US Naval Observatory pointed a telescope roughly in the direction of the constellation Lupus the wolf and took a picture. When scientists look at that same patch of sky today, something is missing, and it could be evidence of something else lurking out there.

Planets around a black hole? Calculations show possibility of bizarre worlds

by Hitoshi Yamaoka, National Astronomical Observatory of Japan, Phys.org

Theoreticians in two fields defied the received wisdom that planets only orbit stars like the sun. They proposed the possibility of thousands of planets around a supermassive black hole.

A nearby river of stars

by Staff Writers, Space Daily

Astronomy and Astrophysics publishes the work of researchers from the University of Vienna, who have found a river of stars, a stellar stream in astronomical parlance, covering most of the southern sky. The stream is relatively nearby and contains at least 4000 stars that have been moving together in space since they formed, about 1 billion years ago.

Cold Dark Matter Is Heated Up By Stars, Even Though It Cannot ‘Feel’ Them

by Ethan Siegel, Forbes

One of the great cosmic mysteries of our time is the presence and existence of dark matter. Unlike normal matter, which is made of known particles that can emit, absorb, or otherwise interact with light and the other known particles, dark matter simply passes through both itself and everything else. It is completely invisible, as far as we can tell, except for one effect: it appears to have a gravitational mass. It affects the curvature of spacetime, and holds galaxies, clusters of galaxies, and the great cosmic web together.

Whirlpool Galaxy: A wonder of stars in space

by Ellen Michals, Todays in Tech

In past, we can only see the sun, the moon, and stars. The advancements in science took place and made people able to see and study the solar system. Further developments made scientists able to study the Milky Way Galaxy. Science is getting advance with time and is finding its way in space step by step. Space is full of different wonders. At present, scientists have found one such wonder named as Whirlpool Galaxy.
