The second data release of ESA’s Gaia mission, made in April, has marked a turning point in the study of our Galactic home, the Milky Way. With an unprecedented catalogue of 3D positions and 2D motions of more than a billion stars, plus additional information on smaller subsets of stars and other celestial sources, Gaia has provided astronomers with an astonishing resource to explore the distribution and composition of the Galaxy and to investigate its past and future evolution.

The majority of stars in the Milky Way are located in the Galactic disc, which has a flattened shape characterised by a pattern of spiral arms similar to that observed in spiral galaxies beyond our own. However, it is particularly challenging to reconstruct the distribution of stars in the disc, and especially the design of the Milky Way’s arms, because of our position within the disc itself.

This is where Gaia’s measurements can make the difference.

Gorgeous, mate!!

edit: ok. 'splain what I'm looking at there?

double edit: went looking, haven't found yet, but did stumble into this page... wonderful look at the stars in the galaxy!

It's the map based on 400000 OB stars [hottest/brightest/most massive stars in our Galaxy] within < 10kly from the Sun.
It is centred on the Sun and shows the Galactic disc as if we were looking at it face-on from a vantage point outside the Milky Way.

Spectacular views. The most enchanting fact for me is retrograde Jupiter of all the times.

It's sad to think how lonely these worlds are... and unimaginative number of them.

How different would our solar system really be if there was one missing? Do they all play a part in making the Earth work? I know Jupiter helps ward off debris.. and the moon with tides.. but what the hell is the point of Mars?

 

[sepheronx]

Yes and no. The current rotation of the planets around the sun is the reason why our world was able to sustain life. If that balance is broken, I believe the rotation would be broken.

That said, it is depressing to see that loneliness. Would be fun to know of other living forms to interact with.

Some fun with NdGT

I don't care what anyone says, I still like Sagan's Cosmos more than Neil's. Even with the outdated info... I must have seen it a dozen times.

Neil has a wonderful, enthusiastic personality though, don't get me wrong.

Very different and Yes. Mars is theorized to have been very Earth-like early in the history of the solar system, which is supported by the information being retrieved by the probes on the surface of Mars. It's very exciting time to be and astronomer/astrophysicist.

Rotation of the Large Magellanic Cloud

Positions and orbits of 20 high-velocity stars were identified using data from the second release of ESA’s Gaia mission. ( @Ahhzz )
The seven stars shown in red are sprinting away from the Galaxy and could be travelling fast enough to eventually escape its gravity. Surprisingly, the study revealed also thirteen stars, shown in orange, that are racing towards the Milky Way: these could be stars from another galaxy, zooming right through our own.

 

[Ahhzz]

Very cool!!!

The Sun has only once been this free of major spots since observation began. Extreme solar storms will be incoming in the next few years.
