Science Magazine: Zoom on the galactic centre

Astronomers have found a dozen very old variable stars deep in the maelstrom of stars at the center of our Milky Way galaxy. The discovery may help researchers decide which of two theories best explains how a “galactic bulge”—the pileups of stars at the galaxy’s center—forms.  

Caltech: The Making of the Milky Way

Simulated view of the formation of our Milky Way galaxy. The simulation begins moments after the birth of the universe 13.8 billion years ago and ends with our mature, present-day Milky Way galaxy. Pockets of matter are seen growing in size, and merging with each other, due to the force of gravity. The clock in …

ESA: First data from ESA’s Gaia mission

Launched in December 2013, Gaia is destined to create the most accurate map yet of the Milky Way. By making accurate measurements of the positions and motions of roughly 1% of the total population of stars in the Milky Way, it will answer questions about the origin and evolution of our home galaxy. The first …

PBS Digital Studios: Space Time | Why is the Earth Round and the Milky Way Flat?

Our universe is not a very diverse place when it comes to shapes. Large celestial bodies become spheres, galaxies become discs, and there is little room for variation. Why is this? Well it turns out physics has some pretty strict rules when it comes to creating new planetary bodies. On this week’s Space Time, the …

ESA: Close look at the ATLASGAL image of the plane of the Milky Way

This video takes a close look at a new image of the Milky Way released to mark the completion of the APEX Telescope Large Area Survey of the Galaxy (ATLASGAL). The APEX telescope in Chile has mapped the full area of the Galactic Plane visible from the southern hemisphere for the first time at submillimetre …

ESO: VISTA finds hidden feature of Milky Way

Astronomers using the VISTA telescope at ESO’s Paranal Observatory have discovered a previously unknown component of the Milky Way. By mapping out the locations of a class of stars that vary in brightness called Cepheids, a disc of young stars buried behind thick dust clouds in the central bulge has been found. This video shows …

Gaia: launch to orbit

Animation showing Gaia launch and journey to its operating orbit. The animation begins by visualising the launch from Europe’s Spaceport in Kourou, French Guiana, on a Soyuz-STB/Fregat-MT vehicle. Watch the full replay of the launch coverage of ESA’s billion-star surveyor Gaia. Liftoff occurred at 09:12UT/10:12CET on 19 December and the successful deployment of Gaia’s sunshield …

Jonathan Fortney: The Typical Planet in our Galaxy?

SETI talks presents Jonathan Fortney who talks about how the NASA’s Kepler Mission has revealed that the most common size of planet in our galaxy may be those from 2-3 Earth radii. Such medium-sized planets are significantly more common on close-in orbits than Neptune and Jupiter-class giant planets. We have no analog for these planets …

Spiral Galaxy, the Milky Way unravelled

By Lighcurve Films: Leiden, April 1953. It took centuries of searching, years of waiting, months of observing and weeks of calculating. For the very first time in human history a group of scientists looks at a map: the first map of our Galaxy, our Island in the Universe. These scientists are some of the top …
