2016 was another very good year for the expansion of our knowledge of the Universe.
Inside the Solar System we have:
• A solar flare
• Mars at opposition
• Juno reached Jupiter
• Rosetta ended
In the Milky Way we have:
• Major data from Gaia
• Updates on several nebula and star clusters
• A close look of the Crab Nebula pulsar
• The discovery of a new Magnetar
We’ll
go into what a magnetar is which will also lead us into a deep dive on
how we used radio astronomy to piece together our galaxy’s rotation
curve.
Beyond the galaxy, we have some beautiful photographs of:
• Nebula inside orbiting galaxies
• The discovery of Eta Carina twins
• A skyrocket galaxy
• A report from a Great Observatories Survey that has changed the number of galaxies we believe exist in the Universe.
We’ll
end with a look at the Palomar Observatory and its new Zwicky Transit
Facility that can cover the whole sky in 8 hours; compare one day to the
next; and report differences of any kind. It’s great for finding things
like distance supernova to nearby asteroids.
