Teleskop Webb deteksi galaksi tanpa rotasi dari alam semesta awal

Para astronom yang menggunakan Teleskop Luar Angkasa James Webb telah mengidentifikasi sebuah galaksi masif yang tidak menunjukkan rotasi, yang terbentuk kurang dari 2 miliar tahun setelah Big Bang. Temuan ini menantang model evolusi galaksi yang ada saat ini.

Galaksi tersebut, yang dikenal sebagai XMM-VID1-2075, memiliki jumlah bintang beberapa kali lipat lebih banyak daripada Bimasakti dan telah berhenti membentuk bintang baru. Peneliti utama Ben Forrest dari University of California, Davis, menggambarkan ketiadaan rotasi tersebut sebagai sesuatu yang mengejutkan dan tidak terduga untuk objek sedini itu.

Astronomers using the James Webb Space Telescope have identified the farthest jellyfish galaxy observed to date, located at a redshift of z=1.156. This galaxy, viewed as it appeared 8.5 billion years ago, features trailing streams of gas and young stars shaped by ram-pressure stripping in a dense cluster. The finding suggests that early universe galaxy clusters were more turbulent than previously thought.

A galaxy named Hebe, observed 400 million years after the Big Bang, shows evidence of pristine Population III stars formed solely from hydrogen and helium. Researchers led by Roberto Maiolino at the University of Cambridge used the James Webb Space Telescope to confirm spectral lines indicating extremely hot, massive stars. The finding offers insights into the early universe's star formation.

Astronomers have found evidence suggesting that the Sun participated in a large-scale migration of similar stars from the Milky Way's inner regions about 4 to 6 billion years ago. This movement likely carried the solar system to a calmer part of the galaxy. The discovery comes from a detailed study of solar twins using data from the European Space Agency's Gaia satellite.

Astronomers have produced a detailed map of the Milky Way's magnetic field, revealing a surprising diagonal reversal in the Sagittarius Arm. The findings, based on new radio telescope data, help explain how this invisible force structures the galaxy. Led by scientists at the University of Calgary, the studies were published this month in The Astrophysical Journal.
