Spacefarers: How Humans Will Settle the Moon, Mars, and Beyond
6th April
Speaker: Christopher Wanjek Description: More than 50 years after the Apollo 11 moon landing, why is there so little human presence in space? Will we ever reach Mars? What will it take to become a multi-planet species, colonizing the Solar System and traveling to other stars?

Abundances in Przybylski's star ( per-zib-ill-skee)
This looks like a really interesting paper, published on Oxford Academic [1], examining, what appears to be the unusual composition of Przybylski's star [2]. According to Wikipedia [3]* is in the “Southern constellation of Centaurus”
There seems to be quite a few heavier element detected.

The Hubble Space Telescope: From Cosmological Conflict to Alien Atmospheres
Write up : 7th March 2021
This is a really interesting talk and overview of what the HST has undertaken since launch in 1990.
Some highlights
The talk also makes reference to academic papers, which can be easily searched for, so for example
With the last point in the list above, this paper was De Wit, et al 2016 Nature 537,69 – if you search for this you find arxiv 1006.01103 which is publication in the above journal 2016Natur 537
The 537 refers to the volume, and 69 is the first page of the article, in this case the article is on pages 69 to 72.
So using the references from the talk you can do further reading.
Well worth watching

February STSCI lecture review
This months lecture Milky Way vs Andromeda: When galaxies collide. was really interesting, and covered material about how galaxies are formed, looking for life and what may happen when in 7 billion years, the Andromeda galaxy merges with our own, home galaxy.
The lecture also talked about how galaxies were first discovered and how, only in the last 100 years have we really started to learn a lot more about them. Why the two will merge is linked to the expansion of the universe.
Earth, of course, won't exist by then. The sun, being 4 billion years old, will have expanded to a red giant. As the duration of a 'main sequence star' is about 10 billion years (cite OU Open Learn The Sun)
So the lecture also included about how we could find earth 2.0, the fact that this. may not be easy given the time it will take to reach even the nearest start.
Proxima Centauri (4.2ly) and the planet around that isn't very hospitable.
Personal comment to add to this
I would guess it also raises the question if it will take 10's of 1000s of years to reach will it be the same or have developed to be more life friendly, then on the other side of that a planet that is life friendly now, may like the Earth not be so friendly i 1000's of years time.
Looking forward to the next lecture in March.
