Some of the Milky Way's oldest stars aren't where we expect them to be.One of the ways we categorize stars is by their metallicity. That is the fraction of heavier elements a star has compared to hydrogen and helium. It's a useful metric because the metallicity of a star is a good measure of its age. The hydrogen and helium we see in the Universe were created in the early moments of the . That's why they are so plentiful. Heavier elements such as carbon and iron are created through astrophysical processes such as the fusion of elements in stellar cores, or during the collisions of...…Some of the Milky Way's oldest stars aren't where we expect them to be.One of the ways we categorize stars is by their metallicity.

Does it feel like all eyes are on these days? The discovery of the potential biomarker phosphine in the planet's upper atmosphere last month garnered a lot of attention, as it should. There's still some uncertainty around what the phosphine discovery means, though. Now a team of researchers claims they've discovered the amino acid glycine in Venus' atmosphere.The paper announcing the finding is titled ''. The lead author is Arijit Manna, a Ph.D. Research Scholar in the Dept. of Physics at Midnapore College in West Bengal, India. The paper is at the pre-print site arxiv.org, which means...…Does it feel like all eyes are on these days?
