Skyrocket Galaxy Discovered by Hubble

July 5, 2016 By Germaine Hicks Leave a Comment

skyrocket galaxy Kiso 5639

The skyrocket galaxy observed by Hubble is located 82 million light away from Earth.

The Hubble Space Telescope discovered a skyrocket galaxy spreading fireworks into the deep dark space.

The Kiso 5639 galaxy shines brightly as new stars are being born on one side of its gravitational field. Its plate shape and its tilt, together with the spark of the new stars, make it resemble a skyrocket.

The galaxy is located 82 million light away from Earth, in an area very poor in gas. German scientists from the Heidelberg University believe that Kiso 5639 encountered a mass of gas which triggered the formation of new stars on one of its edges.

The elongated galaxies are abundant, but they are also very distant to Earth. Astronomers think that the star birth lights are enhanced by the intergalactic gas which may be situated on one of the galaxy’s sides.

The researchers studying the star formation believe that this type of galaxy was very common in the early days of the Universe. The theory says that all galaxies were formed through the accumulation of gas, which in conjunction with star birth can create an incredible display of light.

Even though scientists believe that almost ten percent of the galaxies have elongated shape, only a few of them had been observed until now.

The creation of such elongated gravitational fields of stars can take much more time than the rest of the galaxies.

The team of researchers from the Vassar College in New York has studied the Kiso 5639 galaxy in hope they will uncover the secrets of the birth of the Universe. They used the Hubble’s data to determine the mass and the age of the stars.

An international team selected ten tadpole galaxies, including Kiso 5639, and reached the conclusion that the gas distribution is not uniform. On the brighter side, the universe contains mostly hydrogen and fewer heavy elements than the darker side.

One explanation may be that the heavy elements are only released after the death of the star, and the head of the skyrocket galaxy contains only young stars.

The young star clusters from Kiso 5639 have an age of 1 million years, and they are up to six times larger than the older stars from the same galaxy. The darker side of the galaxy fosters stars that are a billion years old.

Another interesting fact revealed by Hubble is the presence of giant holes in the gas surrounding the young stars. Scientists believe that these anomalies are created by the rarefied gas left behind the supernova detonations.

Even if for now the lack of balance made people compare it to a skyrocket galaxy, the researchers expect that the situation will change in the future. The universe will continue to spin and expose different parts of its surface to the gas deposit, which will make new stars spark all around it.

Milky Way Might Be Dying but There Is a Cure

January 31, 2016 By Chen Lai Leave a Comment

"Milky Way"

Our galaxy is either dying or already dead, but the Smith Cloud might revive it.

Latest astronomical measurements established that the Milky Way might be dying but there is a cure in the form of a gas cloud that is approaching our galaxy.

A professor at the Zurich Institute of Technology from Switzerland, Kevin Schawinski started a collaboration with other scientists in order to begin the work on a classification of galaxies, especially focusing on their shape.

According to their findings, the shape of a galaxy can determine its lifespan. After applying the new information on the Milky Way, the scientists discovered that there are two possibilities either the galaxy is shutting down slowly, or it has already died and we are living in a sort of zombie galaxy.

The Milky Way might be dying but there is a cure. A galaxy feeds on hydrogen gas, and the astronomers have found a huge cloud of the desired gas heading our way. This could revive the Milky Way, extending its life expectancy with a few more billion years.

The hydrogen gas is needed because it is the raw material from which stars are formed. When a galaxy runs out of hydrogen gas, the process that allows stars to be formed is ceased. And seen as stars have a limited life span, a galaxy will only continue to survive for as long as the hydrogen burning giants continue to burn. After that, all of the stars that will die will collapse and form a black hole which will slowly engulf the entire galaxy.

There are three different color codes when it comes to categorizing a galaxy. The blue galaxies which are young, and the majority of the stars are still forming, the red galaxies in which a great part of the stars are already formed, and the green galaxies which that are on the brink of death. The Milky Way falls into the third category.

But fear not, Milky Way might be dying but there is a cure and it was captured by the Hubble Telescope not long ago. The cloud of hydrogen gas that is traveling at a high speed and heading right towards our galaxy was named the “Smith Cloud”.

According to the scientists, the cloud may have been a part of the Milky Way 70 million years ago, and now the prodigal cloud –son returns just in time after gathering enough helium and hydrogen to help the mother galaxy give birth to approximately 2 new million suns.

The cloud is an important example of how galaxies change over time. Milky Way might be dying but there is a cure, the galaxy just has to hang on a couple dozen million years or so.

The Smith Cloud is estimated to reach the Milky Way in almost 30 million years.

Blasting Stellar Fireball: Caught On Camera For The First Time

October 27, 2014 By Germaine Hicks 11 Comments

Blasting-stellar-fireball

Recently, the first time-lapse images of a thermonuclear fireball blasting out of a nova star have been captured by the astronomers.

An international team of researchers worked together to map the nova eruption, a baby brother to a supernova explosion. The study is published in the Nature journal.

Professor Peter Tuthill of the University of Sydney’s Institute for Astronomy stated that, “Although novae often play second fiddle in the popular imagination to their more famous big cousins – the supernovae – they are a truly remarkable celestial phenomenon.”

When a striking, compact star known as white dwarf shreds the matter from a nearby companion star with its intense gravitational field, Novae happen.

The white dwarf frequently sucks hydrogen from its partner, forming an ocean on its surface similar to the little stellar mosquito . After forming about as much mass as the entire planet Saturn, the pressure reaches a critical point, then bang!

Professor Tuthill said, “The stellar surface turns into one titanic hydrogen bomb throwing a fireball out into space and pushing a previously faint, murky star system into eminence as a nova in our night skies.”

However, the rage of the expansion is breathtaking, surrounding an area the size of the Earth’s orbit within a day, and passing Jupiter’s orbit in less than two weeks. In spite of the massive size of the fireball, at the remotest distance to this star of 15000 light years, it took very special technology to be able to image it at all.”

The team of researchers collaborated with the Georgia State University scientists, running the Centre for High Angular Resolution Astronomy (CHARA) array in Southern California, in order to make the fine measurements necessary to map the event.

Dr. Vicente Maestro, also of the University of Sydney, said, “The technical challenge posed requires the magnification equivalent to watching a flower in my Spanish hometown of Algeciras open out from here in Sydney, a distance of 12,000 kms away.”

The array took the first pictures of a nova at the early fireball stage from one that exploded in the Delphinus constellation last year, from Earth’s point of view. In reality, the star went nova 15,000 years ago, but the star is 14,800 light years from our Sun so we only spotted it last August.

However, the observations were quite clear and showed how the structure of the ejected material evolves as the gas expands and then cools. This study eventually reveals that, this expansion is more complicated than the simple models formerly predicted.

As per the first observation, the fireball was roughly the size of Earth’s orbit. When last measured, 43 days after detonation, it had expanded nearly 20-fold at a velocity of more than 600 kms per second to nearly the size of Neptune’s orbit, the outermost planet of our Solar System.

But, the explosion was not exactly circular, instead the fireball had a slightly elliptical shape. The researchers also found that the outer layers of the eruption became more diffuse and transparent as the fireball expanded. Just after a month, the researchers observed a brightening in the cooler, outer layers, potentially caused by the formation of dust grains that spew light at infrared wavelengths.

Dr Theo ten Brummelaar of Georgia State University stated that, “The recent information enable us to study in detail exactly how the fireball evolves as the gas expands and cools. It seems like the ride is a lot more complex and jarring for the gas than the simple models used previously would have predicted.”

Perhaps most shockingly, the astronomers discovered that regardless of the rage of the detonation on the white dwarf’s surface, the star itself emerges almost intact, leaving it free to start the whole process all over again.

Milky Way Galaxy Bullies Hydrogen of Nearby Dwarf Galaxies

October 18, 2014 By Rebecca McGhee Leave a Comment

Milky-way-galaxy-bullies-hydrogen

In early September, the astronomers determined that the Milky Way galaxy is bullying hydrogen gas from close by spheroidal dwarf galaxies, which is compulsory for the creation of stars. Thus, the Milky Way’s closest galactic neighbors will not be able to make stars. Conversely, this doesn’t happen with the dwarf galaxies beyond our neighborhood. They can produce plenty of Hydrogen, that’s why they have the ability to form plenty of stars.

The Milky Way galaxy, is part of a ginormous supercluster of galaxies, which were named “Laniakea,” Hawaiian for “immense heaven” that are held together by gravity. The Milky Way is the bigger galaxy and others are dwarf galaxies. After the formation of galaxies, the remnants’ group together and form the spheroidal dwarf galaxies. Ahead of the monarchies of the dwarf galaxies are misshaped dwarf asymmetrical galaxies that are not the part of the group.

Kristine Spekkens, lead author of the new study stated, “Astronomers speculated if, after billions of years of interaction, the close by dwarf spheroidal galaxies have all the same star-forming ‘stuff’ that we find in more distant dwarf galaxies.”

The remote asymmetrical dwarf galaxies have lots of neutral hydrogen gas, though there is no clear indication about the nearby dwarf galaxies yet. The astronomers explored that spheroidal dwarf galaxies were devoid of any signs of hydrogen gas with the help of large telescopes around the globe including the National Science Foundation’s Green Bank Telescope.

At first, it was believed that the close by black hole was actually sucking the hydrogen gas from the spheroidal galaxies. Though, afterwards it was observed that the Milky Way galaxy is bash reverse as compared to the dwarf galaxies. The Milky Way galaxy is situated in the center of a dense halo of Hydrogen Plasma that expands for thousand of light years. So, eventually the huge halo in addition to the high-speed of the spheroidal dwarf galaxies orbiting around the Milky Way was stripping away their hydrogen.

According to the recent reports revealed, there is an indication that the Milky Way galaxy is stripping off hydrogen gas from close by spheroidal dwarf galaxies which is compulsory for the creation of stars.

Leaky Galaxy May Fling Some Light On The Universe Evolution

October 11, 2014 By Jason Leathers 3 Comments

Leaky-Galaxy

About 400 million years ago, the universe was very dark until the first star producing galaxies started to make ultraviolet light, which ultimately lighted up the cosmos.

Recently, NASA-funded research team with grant number 12886 at the Johns Hopkins University discovered a compact galaxy named as J0921+4509. The researchers believed that it possesses similar characteristics needed to lighten up the early universe. It is actually emitting photons with an energy that ionize hydrogen atoms. This galaxy also enables over 20% of its ultraviolet radiation to leak through the dust clouds causing it to emit strong levels of ultraviolet light and providing hints to astronomers on how the earliest galaxies of the universe may have likely behaved.

J0921+4509 is located 2.9 million years away from the Milky Way galaxy. It generates stars in a compact region similar to the rate of budding galaxies of earliest times. Moreover, the galaxy whips around 50 stars having the same mass as the sun every year that is 33 times more than the number of stars that the Milky Way produces for the same period.

Brian Siana, an astronomer from the University of California, Riverside stated that, “That’s quite high. This is roughly the fraction that we think all galaxies in the early universe had to have in order to ionize the hydrogen in the intergalactic medium.”

Thousands of years after the Big Bang, the cosmic scattered protons and electrons started to cool and developed the first atom of hydrogen. The fact ultimately resulted in the creation of hydrogen walls along with the clouds of cosmic dust, which has the ability to absorb ultraviolet radiation. This averted light from fleeing and blotched the dark ages of the universe.

With the passage of time, these radiations become too strong that it re-ionized the hydrogen. It actually happens when the photons gather enough energy in order to break up the electrons from the hydrogen atoms, which resulted in lighting up the previously dark universe. The astronomers think that, the radiation that broke electrons come from stellar births, but they are not sure about that.

Sanchayeeta Borthakur, an astronomer from the Johns Hopkins University stated that, “The galaxies contains star forming regions that are wrapped with cold gases so the radiation won’t come out. If we want to know that how the radiation gets out of the galaxy, we need to learn the mechanisms that ionized the universe.” He further stated that, it seems that the newly discovered galaxy might provide some hints concerning how the early universe lighted up.

Moreover, the researchers have been in a long quest of finding a ‘holey’ galaxy to examine how star-produced radiation plays a role in ionization process. For this purpose, the researchers placed the particular galaxy with the help of radiation leak measurement method and Cosmic Origin Spectrograph aboard the Hubble Space Telescope. As per the statement of researcher’s team “a combination of unusually strong winds, intense radiation and a massive, highly star-forming galaxy” for the validity of the indicator.

Borthakur stated that, “The confirmation of the indicator is key and now people can use this indicator to study distant galaxies at longer wavelengths.”

The study is published in the journal ‘Science’.
