The Milky Way is expected to collide with its neighboring galaxies, Andromeda and the Large Magellanic Cloud
in a few billion years.
In this new study, astronomers used Hubble to observe 70 pulsating stars called Cepheid variables in the Large Magellanic Cloud
. The observations helped the astronomers "rebuild" the distance ladder by improving the comparison between those Cepheids and their more distant cousins in the galactic hosts of supernovas.
In this study, Riess and his SH0ES (Supernovae, H0, for the Equation of State) Team analyzed light from 70 stars in our neighboring galaxy, the Large Magellanic Cloud
, with a new method that allowed for capturing quick images of these stars.
In order to gather this new data, Hubble measured the light from 70 stars in a neighboring galaxy, the Large Magellanic Cloud
, that's 162,000 light-years away.
According to a study published in the Monthly Notices of the Royal Astronomical Society, the Large Magellanic Cloud
will catastrophically collide with the Milky Way in 2 billion years.
From Canopus, look roughly in the direction of the south celestial pole for the Large Magellanic Cloud
Our first stop is the well-studied Large Magellanic Cloud
(LMC), which lies at a distance of 165,000 light-years.
After Andromeda and the Milky Way, the Large Magellanic Cloud
and the magnificent spiral galaxy M33 are the next largest in size.
R136 is only a few light-years across and is located in the Tarantula Nebula within the Large Magellanic Cloud
, about 170,000 light-years away.
The cluster - named R136 - is only a few light years across and is in the Tarantula Nebula within the Large Magellanic Cloud
- a satellite galaxy of our own Milky Way.
Some specific topics explored include the supermassive black hole in the Milky Way, optical to near-infrared light curves of classical Cepheids, young stellar objects in the large Magellanic cloud
, dwarf Cepheids in the Carina Dwarf Spheroidal Galaxy, and helium in the Galactic bulge.
