|Quote of the Week|
|It's not important what famous people say. We have to speak about things in the right manner. Not people with no knowledge, like me, talking about something like politics or Coronavirus. My opinion really is not important.|

Voice-over: It's time for Science or Fiction.
Item #1: Astronomers have discovered a new type of pulsar that only pulsates on one side.[note 1]
Item #2: The red giant, Betelgeuse, continues an unprecedented dimming, which recent observations suggest is due to a decrease in intrinsic brightness.
Item #3: Using the ESO Telescope, astronomers have detected an exoplanet where it rains iron.

Today I Learned
- Fact/Description, possibly with an article reference
- A pulsar is not really a star, and Steve erred in using the term "pulsar" instead of "pulsating star", as the article uses. From the second article for Item #1: "Pulsars aren't really stars — or at least they aren't "living" stars. Pulsars belong to a family of objects called neutron stars that form when a star more massive than the sun runs out of fuel in its core and collapses in on itself."
