An article published on October 22, 2019, reported on the detection of 3MM-1, a massive star-forming galaxy about 12.5 billion light-years away that is obscured by clouds of dust. At a mass of about 1010.8 solar masses, it showed a star formation rate about 100 times as high as in the Milky Way.
Scientists have observed in unprecedented detail the birth of a massive star within a dark cloud core about 10,000 light years from Earth.
I don’t think anyone has ever observed a star “turning on” like a switch has been flicked. Even though star formation can happen quite …
Has the formation of a star been observed?
Scientists have observed in unprecedented detail the birth of a massive star within a dark cloud core about 10,000 light years from Earth.
Why the star formation process is rarely observed?
The process of star-formation has traditionally been difficult for astronomers to observe. From the time the knot of dust begins to collapse until the protostar becomes a star, the stellar seed is warming up, but is not hot enough to give out large amounts of visible light.
Has anyone seen a star being born?
Summary: Astronomers have glimpsed what could be the youngest known star at the very moment it is being born. Not yet fully developed into a true star, the object is in the earliest stages of star formation and has just begun pulling in matter from a surrounding envelope of gas and dust.
Has star formation ceased in the Milky Way?
New observations show that fully half of the most massive galaxies lost all their star-forming material by ~3 billion years of age, and they never got it back.
What is the 6th stage of a star called?
Stage 6 – The helium core now starts to contract further and reactions begin to occur in a shell around the core. Stage 7 – The core is hot enough for the helium to fuse to form carbon. The outer layers begin to expand, cool and shine less brightly. The expanding star is now called a Red Giant.
What are the 6 stages of a low mass star?
A smaller star, like the Sun, will gradually cool down and stop glowing. During these changes it will go through the planetary nebula phase, and white dwarf phase. After many thousands of millions of years it will stop glowing and become a black dwarf. A massive star experiences a much more energetic and violent end.
What are the 7 stages of a star?
Massive stars transform into supernovae, neutron stars and black holes while average stars like the sun, end life as a white dwarf surrounded by a disappearing planetary nebula. All stars, irrespective of their size, follow the same 7 stage cycle, they start as a gas cloud and end as a star remnant.
What are the steps of a star life cycle?
Summary. A star begins its life in a nebula, struggles to balance gravitational pull and internal pressure during its main sequence period, and ends its life in an explosion to eventually become a white or black dwarf, or a neutron star, or a black hole.
More Answers On Has Star Formation Ever Been Observed
Star formation – Wikipedia
The formation of individual stars can only be directly observed in the Milky Way Galaxy, but in distant galaxies star formation has been detected through its unique spectral signature. Initial research indicates star-forming clumps start as giant, dense areas in turbulent gas-rich matter in young galaxies, live about 500 million years, and may migrate to the center of a galaxy, creating the …
Study: Star Formation Is Virtually Finished | The Institute for …
First, star formation has never been observed, even in the hot gas clouds in galaxies where it supposedly occurs. Stars could only form in theory through an unlikely nearby star explosion. And then that exploded star would need another earlier nearby star explosion.

New Evidence That All Stars Are Born In Pairs Using NASA’s Chandra X-ray Observatory to observe the high-energy radiation inside star-forming regions. Protostars emit a lot more X-rays than fully-formed stars, and this type of light penetrates dense molecular clouds, enabling astronomers to study newborn stars and their environment.
Astronomers Observe the Birth of a Massive Star in the Milky Way
Using the Atacama Large Millimetre/submillimetre Array, astronomers observed the birth of a massive star within a dark cloud core, revealing in superb detail the filamentary network of dust and gas flowing into the central compact region of the cloud.

Has anyone ever seen a star “turn on”? (Beginner)
I don’t think anyone has ever observed a star “turning on” like a switch has been flicked. Even though star formation can happen quite “quickly” compared to other astronomical events, it still can take hundreds of thousands of years for a molecular cloud to collapse and form stars.
Star Formation – Astronomy
The basic idea of triggered star formation is this: when a massive star is formed, it emits a large amount of ultraviolet radiation and ejects high-speed gas in the form of a stellar wind. This injection of energy heats the gas around the stars and causes it to expand. When massive stars exhaust their supply of fuel, they explode, and the …
Are Stars Still Forming Today? – Answers in Genesis
Most astronomers believe that the universe began in a big bang nearly 14 billion years ago, but they believe most stars can’t be that old because they would burn out. So astronomers generally assume that most of today’s stars formed after the origin of the universe. Indeed, they take it for granted that many stars are still forming even today.
Star Formation and Creation – Answers in Genesis
Astronomers frequently report observations like this of “new stars” or “young stars,” which assume that these stars formed within the last few million years. Astronomers who believe the big bang and today’s other naturalistic origins theories would say stars can form in the present from clouds of dust and gas in space.
Record-Breaking Evidence Just Changed What We Know About Star Birth …
16 MAY 2018 Astronomers using some of the most powerful telescopes on Earth have found evidence that stars were forming incredibly early on in the life of the Universe – just 250 million years after the Big Bang, well before the proverbial dust had settled.

Star Formation – an overview | ScienceDirect Topics
It has been observed (Herman and Marling, 1979) that the addition of buffer gases increases the dissociation yield by large amounts because they significantly increase the coupling of the laser to the spectroscopic gas. A detailed knowledge of the RET process is important to optimize these processes. Similarly, MIRPD can play a role in chemical vapor deposition for amorphous silicon thin films

The formation of stars – ESA/Hubble
To astronomers and laymen alike the topic of star formation has always been a particularly appealing one. The reason being that important clues about our genesis lie hidden behind the veil of the dusty, and often very beautiful, star forming molecular clouds.Our Earth and the Solar System were born 4.6 billion years ago and our knowledge of the event is sparse.

The star formation rate density (SFRD) represents the total star formation occurring per unit time and volume at a given epoch; determining the contribution of infrared galaxies to the Universe’s SFRD has been an important focus of DSFG surveys, particularly in understanding the role of dust obscuration at high redshifts. The SFRD is better constrained than infrared luminosity functions as …

More than 700 newborn stars have been identified inside the Orion Nebula, ranging in age from 100,000 years to slightly over a million years old — a tiny fraction of the Sun’s current 5 billion-year age. While the nebula is visible even without a telescope, the newborn stars aren’t. That’s because gas and dust absorb much of the visible light produced by the stars. All star-forming …
