Exploring the Solar System and Beyond: Hubble's Discoveries and the Search for Life

The video discusses the discovery of distant planets within and beyond our solar system, highlighting Sedna's identification and Hubble's role in detecting extrasolar planets. It also covers the search for life indicators like oxygen and methane in other planets' atmospheres. The video concludes with NASA's decision not to repair Hubble, affecting its future operations.

What was the significant discovery made in 2003 within our solar system?

• Sedna, a distant planet-like object

• A new moon of Jupiter

• An asteroid belt near Mars

• A comet approaching Earth

How do astronomers use the Hubble Space Telescope to find planets outside our solar system?

• By measuring the temperature of stars

• By observing the wobble in stars' positions

• By capturing images of planets directly

• By detecting radio signals from planets

When did Hubble make its first direct detection of an extrasolar planet?

• 2015

• 1995

• 2010

• 2001

What are astronomers looking for in the atmospheres of extrasolar planets to indicate potential life?

• Nitrogen

• Carbon dioxide

• Oxygen or methane

• Water vapor

Why are Hubble's operational days considered numbered?

• It has completed its mission objectives

• It is being replaced by a newer telescope

• It is too far from Earth to maintain

• NASA has decided not to repair its gyroscopes and batteries
