The Moon Might Be More Metal-Rich Than We Thought

The Moon Might Be More Metal-Rich Than We Thought A new study shows that the Moon is more metal-rich than previously thought. That has some far-reaching implications for our understanding of the Moon’s formation. If their results are solid, it means that we may need to re-think the giant impact hypothesis for the formation of […]

Betelgeuse Probably Dimmed Because of Enormous Starspots

Betelgeuse Probably Dimmed Because of Enormous Starspots A few months ago we all watched as Betelgeuse dimmed. Between October 2019 and 22nd of February 2020 the star’s brightness dropped by a factor of about three. It went from magnitude 0.5, and from being the tenth-brightest star in the sky, to magnitude 1.7. Naturally, we all […]

NGC 2275: An Absolute Unit of Galactic Flocculence

NGC 2275: An Absolute Unit of Galactic Flocculence The Hubble Space Telescope has the knack for finding every size and shape of galaxy imaginable – from small, medium to large, all the way up to absolute units. This unusual galaxy, named NGC 2775, is incredibly fluffy-looking, or flocculent. It’s definitely a spiral, but instead of […]
