Betelgeuse Isn’t Just Dim, It’s Lopsided - SciShow News

The video discusses the dimming of Betelgeuse, a red supergiant star in Orion, and explores possible reasons for this change, such as dust clouds or sunspots. It also covers the New Horizons mission's findings on Arrokoth, a Kuiper Belt object, shedding light on planetesimal formation theories. The video highlights the importance of these astronomical observations in understanding stellar and planetary evolution.

What is the significance of Betelgeuse in the constellation Orion?

• It is a newly discovered star.

• It is the closest star to Earth.

• It is a red supergiant nearing the end of its life.

• It is the brightest star in the sky.

What unusual observation has been made about Betelgeuse recently?

• It has started to change color.

• It is dimming and appears lopsided.

• It has become the brightest star in the sky.

• It has moved closer to Earth.

What is one possible explanation for Betelgeuse's dimming?

• A massive solar flare.

• A giant sunspot covering part of the star.

• A nearby black hole.

• An increase in its size.

What is Arrokoth, as explored by the New Horizons spacecraft?

• A newly discovered planet.

• A Kuiper Belt object with a unique shape.

• A distant star.

• A comet approaching Earth.

What is the shape of Arrokoth, as observed by New Horizons?

• Spherical

• Cubical

• Snowman-like with two lobes

• Flat and disk-like

Which theory of planetesimal formation does Arrokoth's structure support?

• Magnetic Attraction

• Tidal Disruption

• Gravitational Instability

• Hierarchical Accretion

What does the similar composition of Arrokoth's lobes suggest?
