When you first see the corpse of Jeremy Harper his right eye moves slightly and his eyes are open. The next time you see his face his eyes are closed.
The story begins with a total eclipse of the sun. The following day it's a full moon which is impossible.
When Barnaby first visits the observatory, there's a transparent writing board with various formulae and writing on it, including the term "Plank's Constant". This famous constant is named after the German theoretical physicist Max Planck and therefore should be spelled "Planck's Constant."
Gagan submits what is supposedly her thesis which is a skinny little sheaf of papers in a Duotang binder. A thesis is a huge book size volume based on years of research. In addition the student works closely with his/her advisor who guides the student so the advisor would not be surprised by the contents as depicted in the show.
The pathologist states that a body may have been moved post mortem, because there was extraneous bruising. A body will not develop true bruising after death, and a pathologist is careful to distinguish the causes of post mortem discoloration.
The plumber/amateur astronomer tells Jones there are billions of galaxies in the multiverse. The multiverse is an unproven theoretical concept which is popular in science fiction and comic books, the correct term is universe.
When Barnaby and Jones visit Adrian Sharpe after Gagan goes missing, a kettle is heard whistling. However, when he takes the kettle off, it does not appear to be a whistling kettle as there is no whistle cap removed. However, there are some styles of kettle which have a whistling flap inside the spout, which would not be visible on camera.
When Mags shows police evidence of the time that she logged off her computer, she displays what is clearly a Windows Explorer list of Word documents (you can see the Word icon and the description "Microsoft Word Document") which have people's names. The entry that she points to is for Ben Jones (Barnaby's sergeant) rather than her own name, and during post-production the normal "Date Modified" column has been given a heading "Logged off at" in a clearly different font. At another point in the conversation she says that she has been working on Jones's star chart, so it is possible that the screen shot was intended to refer to this.
Kate says the laptop had encrypted files that the tech people could not unencrypt, then she says it was astronomical data. If the data was encrpted then it would be impossible for the tech people to know what the files contained.
The yoga instructor tell his class to rub their stomachs in a clockwise direction then demonstrates by rubbing his stomach counterclockwise.
The killer walks away immediately after throwing the spear, but the next day the police say the spear was removed and the body posed.
When D.I. Barnaby asks amateur astronomer George Dormer where he was the previous night when a murder was committed, he replies that he was watching a transit of Venus. This occurs when Venus crosses the disc of the sun, and it would be impossible to see such an event at night.
Adrian Sharp describes Heisenberg's Uncertainty principle as "how you look at things effects what you think you see." The Uncertainty Principle actually says that it is impossible to measure both the position and momentum of a particle with absolute precision.
What he might have been trying to explain is "The Observer Principle," which states that the act of observation changes the thing being observed, but he gets that wrong anyway.

When Adrian Sharp first speaks to Barnaby at the observatory, he says that the probable fate of Earth will be to be sucked into a black hole. In fact, it is universally accepted by astronomers that Earth will be swallowed up as the sun expands into a red giant in about five billion years' time.
When Mags is trying to convince Jones to take his star chart, she calls him Jason.
Makes no sense for a chemist to take away the condoms from his 21 year old daughter. HIV or unplanned pregnancy are better that admitting she's an adult woman.
