Our First Glimpse of a Newborn Supernova - SciShow News

The video discusses recent astronomical discoveries, including the observation of a supernova named AT2018cow, also known as the Cow, which may represent the birth of a black hole or neutron star. This event was unique due to its brightness and short duration. Additionally, a binary star system with a perpendicular protoplanetary disc was discovered, challenging previous theories. These findings provide new insights into stellar phenomena and the formation of solar systems.

What was the initial reaction of astronomers to the signal named AT2018cow?

• It was immediately classified as a black hole.

• It was considered a super bright transient phenomenon.

• It was thought to be a new type of star.

• It was identified as a typical supernova.

What makes the Cow event significant in the study of supernova remnants?

• It was the first supernova to be observed from space.

• It was the first time a supernova remnant was observed in multiple types of light.

• It was the first supernova to be observed in the Southern Hemisphere.

• It was the first supernova observed in infrared light.

What was unique about the binary star system discovered recently?

• The stars orbited each other in the same direction as the disc.

• The stars were the largest ever discovered.

• The disc of dust and matter orbited perpendicularly to the stars.

• The system was located in a different galaxy.

What tool did astronomers use to observe the binary star system with a perpendicular disc?

• Hubble Space Telescope

• Kepler Space Telescope

• Atacama Large Millimeter/submillimeter Array

• Very Large Telescope

What does the discovery of the perpendicular disc in a binary star system suggest?

• Such systems are extremely rare and unlikely to be found again.

• Perpendicular discs could be relatively common in the universe.

• The disc will never form planets.

• The stars will eventually collide with the disc.
