The ‘Magellanic Stream,’ a 600,000 light-year-long gas trail, stretches from the Magellanic Clouds, discovered in 1974. It’s being pulled by the Milky Way’s gravity, showing galactic interactions.Some astronomers think it’s enriched with metals from past star formation.

Fragmentos de Alpha Centauri podrían estar en el Sistema Solar Astrónomos canadienses han calculado que, en los últimos 110 millones de años, alrededor de 1 millón de partículas de más de 100 metros podrían haber entrado en la Nube de Oort desde el sistema estelar más cercano: Alpha Centauri. La Nube de Oort es una región esférica gigante alrededor del Sistema Solar llena de cuerpos helados, desde donde se originan muchos cometas de período largo. Partículas más pequeñas, de unos 3,3 micrómetros de tamaño, también podrían haber atravesado el espacio interestelar, pero son bastante difíciles de detectar. Los investigadores creen que alrededor de 10 fragmentos de Alpha Centauri se queman en la atmósfera de la Tierra anualmente, convirtiéndose en meteoros visibles. Estos fragmentos podrían proporcionar a los astrónomos información valiosa sobre la composición de los exoplanetas en ese sistema estelar.

🚀 The First Crewed Lunar Mission in 54 Years, Artemis II, Has Launched At 6:35 p.m. Eastern time, the SLS rocket carrying the Orion spacecraft lifted off from Launch Complex 39B at NASA's Kennedy Space Center in Cape Canaveral, Florida. Four astronauts—Reid Wiseman, Jeremy Hansen, Christina Koch, and Victor Glover—will fly around the Moon and return to Earth over the course of a 10-day mission. In 2028, as part of the fourth Artemis mission, astronauts are expected to land on the Moon. ⏳ Before Artemis, the last crewed lunar mission was Apollo 17. In 1972, American astronauts landed on the Moon for the sixth time, a feat that remains the most recent lunar landing to this day. Do we need more missions to the Moon? ❤️ — Yes, it is our base for space exploration 🔥 — No, we should focus on Earth

NASA's Artemis 2 mission has been launched!
