 Why in news 

  • The Bengaluru-based Indian Institute of Astrophysics (IIA) has filmed the passing of the moon in front of Antares, a bright red star.

  • The moon passed in front of Antares on April 27, hiding it for roughly 40 minutes

  • IIA said that this event was visible only from southern India

  • IIA filmed the event from its Bengaluru campus using a camera on an 8-inch telescope.

  • The word "Antares" written in pink on a gray background is what the image you sent me depicts

  • Antares is not just a word, it refers to the brightest star in the constellation Scorpius

  • It is a red supergiant, a large and relatively cool star that is hundreds of times larger than the Sun

  • Antares is located approximately 570 light-years away from Earth.

  • Its diameter is estimated to be around 700 times larger than the Sun.

  • Although a red supergiant, Antares is the 16th brightest star in the night sky despite its distance because of its immense size.

  • While appearing red to the naked eye, it actually emits mostly green and yellow light

  • The reddish hue we see is a result of dust in space absorbing these colours and scattering the red wavelength towards us.
