I've compiled an entire years' worth of astronomy stories with summaries and links to the proper source. So take a look and perhaps get through it in chunks since 2016 was an eventful year for astronomy :)

New article! "How Direct Fusion Drive (DFD) will Revolutionize Space Travel" This technology could cut travel time by half! We could get to Mars in just a few months.

This is a beautiful cosmic family portrait of what is known as the "*Sagittarius Sunflower*." What you are looking at are 3 distinct cosmic nebulae. On the left we have the famous M8 or "Lagoon Nebula," located about 4,400 light years from Earth. This nebula alone is about hundreds of light years across or about 1 quadrillion KM. To try and put that in perspective, if we travelled at 50 km/s (which we have before) it would take us 5 trillion hours or 26 million years!! And this is in our own Milky Way. We haven't even left our neighborhood!

On the bottom we have M20 or the "Trifid Nebula," located 5,200 light years from Earth. Finally on the right we have NGC 6559 located 5,000 light years away. This narrowband data records ionized hydrogen, oxygen, and sulfur atoms radiating at visible wavelengths.

New NASA mission called TESS set to launch in 2017-2018 will help usher in a new generation of disocovering exoplanets. Not only that but will also look at distant black holes and nearby supernovae. This thing is cool!

Juno Spacecraft: understand the evolution and origins of Jupiter which in turn will help us understand where to look for life elsewhere in the universe.

Arrives: July 4th, 2016

Fun facts: Only powered by solar energy, will take a look at northern and southern lights near Jupiter's poles (first time), and will answer the question "What is Jupiter's core made out of?" ..possibly hydrogen in a 4th state of matter! Something straight out of sci-fi!

Hope you enjoy my post. I tried to make it as fun as possible. Let me know what you think!

Say hello to the beautiful Boomerang Nebula or also known as the Bow Tie Nebula. This is the coldest region we have found thus far in the universe. I'm not sure if we could find any nebulae that are colder because it's literally 1 degrees kelvin! Meaning one degree above absolute zero!

The reason it’s so cold starts with the core of the star (which is right in the middle of the bow) is collapsing on itself, and causing an incredible outflow of gas. The speed of this expansion gas is travelling at an astonishing 164 km/s! Since it’s travelling so fast two things are happening here. One is the gas is cooling down much more efficiently and the other is that the star itself is losing 1/1000th of a solar mass each year. This is 100 times more than what an average star loses during this period.

We wouldn’t have to travel outside of our neighborhood either as it’s located right in our Milky Way 5,000 light years away from Earth in the constellation Centaurus.

Probably lots of guides out there but here's my FYI post on the wonderful transit of Mercury happening tomorrow. Don't miss it space fans!

Here's a gorgeous look at HCG 91, where galaxies are in the process of merging. Over time they will form one larger galaxy which is the same journey our very own Milky Way Galaxy formed. Also, this picture is much deeper and actually shows faint galaxies that are also merging, located 2 billion light-years away from Earth!

A gorgeous supernova remnant called Simeis 147 or the Spaghetti Nebula, that left behind a pulsar. This remnant is located right in our Milky Way and the expanding remnants is travelling at an incredible 950 kilometers per second!
