The Hubble Space Telescope, the “younger cousin” of the James Webb Super Telescope, continues to make unprecedented and astonishing records of our universe.
This week, Hubble released a dazzling, colorful image of space structure and new data on the cosmic history of a supergiant star, proving that the instrument launched by NASA in 1990 is timeless and still important to science. (See more below).
The film was jointly released by NASA and the European Space Agency (See image above) Shows the region of the Orion Nebula (a site of star formation) around the object Herbig-Harrow HH 505, ca 1,000 light years from Earth.
The US space agency explains that these are regions of nebulosity associated with newborn stars. They form when the stellar winds, or jets of gas, ejected from these stars create shock waves that collide with gas and dust at very high speeds.
“These ejected winds are visible as beautiful curved structures at the top and bottom of this image. Their interaction with the large-scale flow of gas and dust from the nebula’s core distorts them into sinusoidal curves,” explains NASA.
Still according to NASA, the image was captured by the Hubble instrument, which examines large areas of space in great detail.
It was captured by astronomers studying the properties of these high-energy currents.
Betelgeuse: A red supergiant star
Just this week, after analyzing scientific data from Hubble and several other observatories, a group of astronomers also revealed a red supergiant star. BetelgeuseOne of the most massive stars ever known, produced a gigantic explosion That’s 400 billion times more than the kind of emissions caused by our star, the Sun (See image below).

In the process, NASA revealed in a statement, the star lost a significant portion of its surface, ejecting a giant mass many times the size of our Moon.
NASA explains “Something never seen before in the behavior of a normal star” Located 530 light-years away from Earth, the red supergiant is still slowly receding from it “Disastrous Turn”.
“We have never seen a massive mass ejection from the surface of a star,” said Andrea Dupree, a scientist at the Harvard-Smithsonian Center for Astrophysics in Massachusetts, US.
“This is a completely new phenomenon where we can directly observe and resolve surface details with Hubble. We are observing stellar evolution in real time.”
Betelgeuse is one of the brightest stars in the night sky. The star is so massive that if it were to replace the Sun at the center of our solar system, its outer surface would extend beyond the orbit of Jupiter.
According to NASA’s statement, the ejection of material took place 2019Lasting for several months, it was easily noticed even by amateur observers, because, when moving at a distance of millions of kilometers from the star, the ejected material formed into a cloud of dust, which blocked the light of the star on Earth.
According to NASA’s statement, the James Webb Super Telescope may now be able to detect objects ejected by the supergiant, which continues to move.
