2017 was another very interesting year with a number of firsts. We detected our first asteroid from another star; a Type 1a Supernova companion survivor; a star collapse into a black hole without a supernova; a gravitationally lensed Type 1a Supernova; a non-elliptical early dead galaxy; colliding neutron stars; and visual confirmation of a gravitational wave.
Inside the Solar System we have:
- Jupiter picture
- Water vents on Europa
In and around the Milky Way we have:
- Gaia’s view of the LMC
- A type 1a survivor
- A runaway star in the Orion Nebula
- A dark matter study in the Sculptor dwarf galaxy
- Zwicky Transient Facility first light
Beyond the galaxy:
- Gravitationally lensed Type 1a Supernova
- A number of colliding galaxies
- An early dead galaxy with a twist
- Lots of new pictures of distant galaxy clusters
Plus a deeper look at Gamma-Ray Bursts and the gravitational wave from colliding neutron stars.
