6 days ago · Astronomers using NASA’s Hubble Space Telescope have imaged the largest protoplanetary disk ever observed circling a young star. For the first time in visible light, …

The protoplanetary disk may not be considered an accretion disk; while the two are similar, an accretion disk is hotter and spins much faster; it is also found on black holes, not stars.

May 22, 2025 · Protoplanetary disks are a collection of dust and gas around young stars, from which planets form. Observing the dust in these disks is easier because it is brighter, but the …

Nov 7, 2025 · A protoplanetary disk is a rotating disk of dense gas and dust that surrounds a newly formed star. These disks are crucial in the formation of planets, as they provide the raw …

6 days ago · We present high-resolution (≲ 0 1) Hubble Space Telescope/Wide Field Camera 3 imaging of the near edge-on (i ∼ 80°) protoplanetary disk IRAS23077+6707 (“Dracula’s …

Mar 26, 2025 · The discovery of compact protoplanetary disks opens up exciting new avenues for further research. Scientists now have a clearer target when searching for the birthplaces of …

Dec 23, 2025 · Nearly 300 years after Immanuel Kant proposed that our solar system’s family of planets condensed from a flattened disk of gas and dust, NASA’s Hubble Space Telescope …

Jun 24, 2025 · A protoplanetary disk is composed of low-temperature molecular gas and dust, surrounding a protostar. If a planet exists in the disk, its gravity will gather or eject materials …
