Comets can’t explain weird ‘alien megastructure’ star after all
The weirdest star in the cosmos just got a lot weirder. And yes, it might be aliens. Known as KIC 8462852, or Tabby’s star, it has been baffling astronomers for the past few months after a team of researchers noticed its light seemed to be dipping in brightness in bizarre ways. Proposed explanations ranged from a cloud of comets to orbiting “alien megastructures”. Now an analysis of historical observations reveals the star has been gradually...

Mercury, Venus, Mars, Jupiter & Saturn all align for first time in 11 years
Earthlings can now observe a rare celestial gathering: Mercury, Venus, Mars, Jupiter and Saturn are all in alignment in our sky - and will continue to be for around a month. The last time the five paraded in a line was December 2004 to January 2005. From January 20 to February 20 sky-gazers can see the five planets almost literally lined up, as their positions along the ecliptic (the sun’s perceived path in our sky) form a diagonal line.

Tarantula Nebula: Hubble spots nine 'monster' stars with masses 100 times that of the Sun
The Hubble Space Telescope has identified nine monster stars in outer space, all with a mass of over 100 times that of the Sun. The stars are part of the cluster R136, and have become the largest group of massive stars ever found. The star cluster is located 170,000 light years from Earth, and the findings will help astronomers learn about the origin of giant stars. The report was published in the Monthly Notices Of The Royal Astronomical Society.
