The Eta Aquarid meteor shower peaks May 6. Here’s what to expect from the ‘crumbs’ of Halley’s Comet

NeRD

Among the top 10 meteor showers appearing annually, one of the best will be reaching its peak on Tuesday morning (May 6). The Eta Aquarid shower ranks among the top four in terms of overall activity. Because the meteors appear to emanate from a spot on the sky (called the “radiant”) in the Water Jar of the Aquarius constellation — hence the name “Aquarids” — their visibility favors prospective skywatchers south of the equator. Indeed, for those living in the Southern Hemisphere (Santiago, Johannesburg Melbourne, Auckland), the Eta Aquarid radiant…

May’s Night Sky Notes: How Do We Find Exoplanets?

NeRD

4 min read May’s Night Sky Notes: How Do We Find Exoplanets? Astronomers have been trying to discover evidence that worlds exist around stars other than our Sun since the 19th century. By the mid-1990s, technology finally caught up with the desire for discovery and led to the first discovery of a planet orbiting another sun-like star, Pegasi 51b. Why did it take so long to discover these distant worlds, and what techniques do astronomers use to find them? The Transit Method A planet passing in front of its parent star…

NASA Kicks Off Biological Research Aboard Space Station

NeRD

Crew members are kicking off operations for several biological experiments that recently launched to the International Space Station aboard NASA’s 32nd SpaceX commercial resupply services mission. These include examining how microgravity affects production of protein by microalgae, testing a microscope to capture microbial activity, and studying genetic activity in biofilms. Microalgae in microgravity Sophie’s BioNutrients This ice cream is one of several products made with a protein powder created from Chlorella microalgae by researchers for the SOPHONSTER investigation, which looks at whether the stress of microgravity affects the algae’s protein…

How to see a celestial ‘gazelle’ cross the night sky close to the Big Dipper this week

NeRD

With the constellation Ursa Major high in the sky, late April presents an ideal opportunity to spot the ‘Three Leaps of the Gazelle’ asterism – a set of three stellar pairings hanging below the Great Bear‘s most famous feature: the seven stars of the Big Dipper. The first mention of the Three Leaps of the Gazelle asterism was seemingly penned by the 13th century Arabic astronomer and mathematician Ulugh Beg, according to a 2021 post from the University of Arkansas at Little Rock. The three star pairings – an asterism…
