Open scan (p.5)

Main Body

Gravitational waves are ripples in space time created due to violent & extreme events in universe.

Hubble telescope was launched in 1990 to study deep universe.

Black holes are region is space with huge density/mass through which even light can't escape.

Recent advancements:

1Gravitational waves → Recently very low frequency gravitational waves were detected by studying Pulsars (rotating neutrons) → A new LIGO observator was approved in Hingoli district of Maharashtra to study gravitational waves.
2Hubble telescope : has recently discovered ultra massive blackhole.
3Black holes : Recently find ever image of black hole was created by Event Horizon Telescope project.

Significance in understanding universe

1Unexplored regions : part of universe not detected by electromagnetic spectrum can be known by gravitational waves.
2Dark energy : which is driving expanding of universe can be better known
3Dark matter : 95% of universe can be explored.
4Gravitational lensing : Black holes can give powerful insights into original universe.

Recently James Webb telescope was launched as complementary to Hubble telescope, which along with other development is unfolding mysteries of universe.
