Nancy Grace Roman Space Telescope

About Nancy Grace Roman Space Telescope: 

• It will provide one of the deepest-ever views into the heart of our Milky Way galaxy.
• Objectives: The mission will monitor hundreds of millions of stars in search of tell-tale flickers that betray the presence of planets, distant stars, small icy objects that haunt the outskirts of our solar system, and isolated black holes.
• Instruments of Telescope
  • Wide Field Instrument: It will have a field of view that is 100 times greater than the Hubble infrared instrument, capturing more of the sky with less observing time.
  • It will measure light from a billion galaxies over the course of the mission’s lifetime.
  • It will perform a microlensing survey of the inner Milky Way to find ~2,600 exoplanets.
  • Coronagraph Instrument: It is a technology demonstration which will perform high contrast imaging and spectroscopy of individual nearby exoplanets.
• Its Galactic Bulge Time-Domain Survey will focus on the Milky Way.
• For this, it will use infrared vision to peer through clouds of dust that can potentially block the view of the crowded central region of our galaxy. 
• This telescope plans to capture this by taking an image every 15 minutes around the clock for about two months.
• This process will be repeated six times over Roman’s five-year primary mission, which will total more than a year of observations.

Q1:What is a Neutron Star?

Neutron Star is an extremely dense and compact celestial object that forms when a massive star runs out of fuel and collapses under its own gravity.
