A #Protostar is the earliest stage of stellar evolution, formed when a dense pocket within a molecular cloud collapses under its own gravity to create a hot, glowing core.
Though it shines brightly from the kinetic energy of infalling gas and dust, it is not yet a true star because it has not yet reached the temperatures required to trigger nuclear fusion.

#PhotoOfTheDay: NASA’s James Webb Space Telescope Finds Crystal-Spewing #Protostar
The NIRCam (Near-Infrared Camera) on NASA’s James Webb Space Telescope captured the actively forming protostar EC 53 (circled at left) in the Serpens Nebula in this image.

A #Protostar is a very young star that is still gathering mass from its parent molecular cloud. The protostellar phase is the earliest one in the process of stellar evolution.
For a low-mass star (i.e. that of the Sun or lower), it lasts about 500,000 years.

#PhotoOfTheDay:L1527 (MIRI image)
L1527, shown in this image from the NASA/ESA/CSA James Webb Space Telescope’s MIRI (Mid-Infrared Instrument), is a molecular cloud that harbors a #Protostar.
It resides in the constellation Taurus, about 460 light-years from Earth.

A #Protostar is a very young star that is still gathering mass from its parent molecular cloud. It represents the earliest phase of stellar evolution, before nuclear fusion begins in its core.

IRAS 04302+2247 is a young #Protostar located about 525 light-years away in the Taurus star-forming region, renowned for its striking "edge-on" view.
This unique orientation reveals a dense, dark protoplanetary disk of dust and gas that blocks the star's light and is believed to be a birthplace for future planets.

🌌🔭 Thanks to the remarkable capabilities of the James Webb #Space #Telescope (JWST), we now have an unprecedented view of a #star in the process of formation.
→ The object in focus is HH 30, a #protostar situated in the Taurus #Molecular Cloud, approximately 450 light-years from Earth.

Identifying the formation period of planetary systems, such as our solar system, could be the beginning of the journey to discover the origin of life.
The key to this is the unique substructures found in protoplanetary disks—the sites of #planet formation.
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 within the disk, forming characteristic substructures such as rings or spirals. In other words, various disk substructures can be interpreted as "messages" from the forming #planets.

A #Protostar is the earliest stage in the formation of a #Star, gradually accreting more material from its surrounding molecular cloud.
It is a large mass of gas and dust that has collapsed inward due to gravity but has not yet begun nuclear fusion in its core.

A #JWST image of Herbig-Haro 49/50 — a frothy-looking outflow from a nearby #protostar — with a multi-hued spiral #galaxy.
Herbig-Haro objects are outflows produced by jets launched from a nearby, forming #star.
The outflows, which can extend for light-years, plow into a denser region of material.
This creates shock waves, heating the material to higher temperatures.
The material then cools by emitting light at visible and infrared wavelengths.

[Observations and #simulations] In addition to #observations of protostars using #interferometers with ever-higher resolution, researchers are developing multidimensional numerical simulations.
The aim is to better understand the formation and evolution of the #protostellar disk and the #protostar through the different phases and scales of the collapse of a dense low- and high-mass core.
This Thursday, Benoît Commerçon, researcher @cnrs at the Centre de Recherche Astrophysique de Lyon (CRAL), will present to IRAPians the results obtained using “his” numerical experiments, as well as future developments ... https://www.irap.omp.eu/event/disk-and-protostar-formation-new-insights-from-3d-numerical-simulations/

A #Protostar is a very young star that is still in the process of forming from a cloud of gas and dust. It's the earliest phase in the life cycle of a star.

#PhotoOfTheDay: LDN 1471: A Windblown Star Cavity
This illuminated cavity, known as LDN 1471, was created by a newly forming star, seen as the bright source at the peak of the parabola.
This #Protostar is experiencing a stellar outflow which is then interacting with the surrounding material in the Perseus Molecular Cloud, causing it to brighten.

[V347 Aur, a #lighthouse in the galaxy] Some stars, like V347 Aurigae, vary greatly in #brightness over short time scales. But why? How? The answer with #SPIRou, the infrared spectropolarimeter installed on the #CFHT : https://www.irap.omp.eu/en/2024/10/spirou-decodes-the-bursts-of-a-protostar/
Around the #protostar V347 Aurigae orbits a brown dwarf of 30 Jupiter masses. Its elliptical trajectory invites the two bodies to periodically move towards and away from each other, generating #instabilities in the #disc of matter that envelops and feeds the nascent binary system. The fall of #matter onto the protostar results in a temporary increase in its luminosity by a factor of 100. Periodic light bursts captured by the SPIRou instrument.

A new image captured by the James Webb Space Telescope reveals new details of a protostar forming within the molecular cloud cataloged as L1527. The MIRI instrument offered new information on the ongoing processes that are leading to the birth of a new star. An accretion disk is barely visible edge-on and is important because the protostar is still absorbing materials from it and planets could form within it in the future.

Just in time for today's solstice, @nasawebb dropped this dreamy #NIRCam image of the Serpens Nebula.
Located 1,300 light-years from Earth, Serpens is home to a dense cluster of very young #stars formed only in about the last 100,000 years.

@Mopsi the #protostar from #prodigy had an extremely small crew, and appears to only have 2 or 3 decks.
the USS Archer in the first episode of #SNW had a complement of 3, which was odd because it appears to have a decent sized saucer section.
The #peregrine attack fighters had a complement of 1 and many of the maquis ships were repurposed starfleet had held 4 or 5 people.

Solving the mystery of how #planets like Earth form is an important question for understanding the origin of life.
Planets are thought to form when interstellar dust and gas collect in a #protoplanetary disk surrounding a #protostar, but it has been unclear how #planet formation begins.
By observing protoplanetary disks without dark rings, astronomers can study systems where giant planets have not yet formed.

It's Like Looking at the Infant Sun: Webb Captures Image of an Energetic Young Star
This new picture from JWST will likely be one of the best pictures released in 2023. It's an example of a Herbig-Haro object, a Type 0 protostar, seen just a few tens of thousands of years after it began formation. The newly-forming star is shrouded by gas and dust but has twin polar jets blasting into space. The star only has 8% of the mass of the Sun right now, but eventually, it'll grow to be roughly the same size and mass as the Sun.
