India's First Dark Sky Reserve to Soon Come up in Ladakh

A part of Changthang Wildlife Sanctuary at Hanle in Ladakh is all set to become India's first Dark Sky Reserve. The site will also promote astronomy-tourism, giving a boost to local tourism through science.
Being a cold desert region, Ladakh holds great potential for undertaking uninterrupted astronomical observations.
At a height of 4,500 metres, Hanle is already home to optical, gamma ray and infrared telescopes at the Indian Astronomical Observatory complex operated by the Indian Institute of Astrophysics (IIA), Bengaluru. These telescopes are in use for studying stars, galaxies, exoplanets and the evolution of our universe.
Hanle is pristine for the dry weather for most months of the year, remains cloudless during nights and offers dark skies – making it a perfect natural setup for sky gazing.

Scientists Discover Tsunami-Like 'Starquakes' In Milky Way

Scientists discovered that stars (or planets) in the galaxy experience "starquakes" that ripple through their surfaces like tsunamis on Earth. The discovery was made by European Space Agency's (ESA's) Milky Way-mapping Gaia mission.
These starquakes are so powerful that they can even change the shape of a star.
The phenomenon was discovered based on data of nearly two billion stars collected by the Gaia space observatory. "Previously, Gaia had found radial oscillations that cause stars to swell and shrink periodically, while keeping their spherical shape. But Gaia has now also spotted other vibrations that are more like large-scale tsunamis.
