The search for evidence of extraterrestrial intelligence is one of the most exciting pursuits in astronomy today. Needless to say, there is a lot of controversy and debate surrounding the topic, partly due to an event which happened in 1977 – the famous “Wow!” signal. The brief but unusual radio transmission was detected only once, and the debate over its origin has continued to this day. Now, a group of astronomers are claiming to have finally solved the mystery. According to their new study just published, the signal came not from aliens, but comets.
The weird star called Boyajian’s Star (aka Tabby’s Star or KIC 8462852) has been fascinating astronomers and people in general because of its weird behaviour of experiencing sudden, unusual dips in brightness which all current theories have so far had difficulty explaining. Now, the star has started dipping again after a long period of “normal” activity.

This is a great 10-part overview of Boyajian’s Star (Tabby’s Star/KIC 8462852) by astronomer and astrophysicist Jason Wright, outlining the various hypotheses to date to explain this weird star observed by the Kepler Space Telescope. Whatever is causing the unusual short-term and long-term dimming is still unknown.
For a long time now, there have been theories and rumors regarding the possible existence of another planet in our Solar System, far beyond Neptune or even Pluto, often referred to as “Planet X.” Unfortunately, there has been little hard evidence to back up any claims made. But now, new evidence has been presented by astronomers at Caltech which increases the likelihood of another, and fairly large, distant planet in the far outer reaches of the Solar System. How does this compare to other discovery claims for Planet X?
There are a lot of books out there about space and astronomy, often focusing on a particular area of research or perhaps sometimes a bit heavy on the technical side. What if you are looking for a book that is appealing to the general public, both visually and information-wise? Something ideal for newcomers to the subject as well as those who already have a good working knowledge about space exploration?
