2017 Update & Gamma-Ray Bursts

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.
