Teleskop NASA Ini Ungkap Rahasia Kelahiran Bintang, Tuai Keheranan


Gambar luar biasa dari Teleskop Luar Angkasa James Webb ini memberikan wawasan baru tentang proses kelahiran bintang. Melalui teleskopnya, ia memperlihatkan protobintang HH 212 yang berjarak sekitar 1.300 tahun cahaya dari Bumi.

HH 212 pertama kali ditemukan pada tahun 1993, terletak di dekat Sabuk Orion dan para astronom telah menghabiskan tiga dekade terakhir mengambil gambar untuk mengungkap bagaimana bintang yang sedang berkembang ini terbentuk secara perlahan.

Namun, menurut Mark McCaughrean, penasihat senior di Badan Antariksa Eropa, ini adalah pertama kalinya para ilmuwan melihat “gambar berwarna yang menakjubkan” dari protobintang, yang sebelumnya tidak mungkin dilakukan dengan teleskop di Bumi.

Gambar baru ini mengungkapkan detail rumit pembentukan bintang, dengan gumpalan simetris gas emisi berwarna merah muda yang berasal dari kedua kutub protobintang. McCaughrean menjelaskan bahwa semburan neon ini, yang dikenal sebagai jet atau aliran keluar, adalah produk sampingan dari kelahiran bintang, dan warna cerahnya menunjukkan adanya molekul hidrogen.
