An Earth-Sized Telescope Just Snapped Two Pictures

The video discusses the challenges of observing black holes, highlighting the Event Horizon Telescope (EHT) project, which aims to capture the first direct image of a black hole. It explains how the EHT uses a network of radio telescopes to simulate an Earth-sized telescope. The video also covers the discovery of atmospheres on exoplanets, focusing on GJ1132B, a Super Earth with a potentially water-rich atmosphere. Despite its high temperature, GJ1132B provides evidence of small rocky worlds with thick atmospheres. The episode concludes with acknowledgments to supporters.

What is the primary goal of the Event Horizon Telescope project?

• To measure the temperature of black holes

• To capture the first direct image of a black hole

• To find new black holes in the universe

• To study the magnetic fields around black holes

How do accretion disks around black holes appear to observers?

• They emit no light at all

• They look brighter where gas and dust move towards us

• They appear uniformly bright

• They are invisible due to extreme gravity

What could an irregular shadow of a black hole indicate?

• A problem with our current theory of gravity

• A malfunction in the telescope

• A lack of an accretion disk

• The presence of multiple black holes

What is significant about the exoplanet GJ1132B?

• It is the first Super Earth with a detected atmosphere

• It is the closest exoplanet to Earth

• It has an atmosphere similar to Earth's

• It is the first exoplanet discovered

Why is detecting atmospheres on exoplanets challenging?

• Their atmospheres are hard to detect due to their small size

• Exoplanets are too far away

• Their atmospheres are too thin

• The light from their host stars is too bright
