Abnormal Star Discovered In The 'Forbidden Zone'
A team of astrophysicists from Germany, France and Italy have discovered in the constellation Leo is an old star.
The star's existence raised at once many questions for scientists.
The object is definitely not as its "contemporaries" that appeared immediately after the Big Bang event.
Proof Of How The Universe Is Changing
Though the universe is filled with billions upon billions of stars, the discovery of a single variable star in 1923 altered the
course of modern astronomy. And, at least one famous astronomer of the time lamented that the discovery had shattered his world view.
Bright Star In The Constellation Lyra Is Cooler Than The Human Body
The coldest class of stars have temperatures as cool as the human body.
Astronomers hunted these dark orbs, termed Y dwarfs, for more than a decade without success.
When viewed with a visible-light telescope, they are nearly impossible to see.
Thermonuclear Burning In A Neutron Star Detected For The First Time!
It's a very important discovery!
For the first time, an international team of scientists have detected all phases of thermonuclear burning in a
neutron star, located close to the center of the galaxy in the globular cluster Terzan 5.
Extremely Distant And Exotic Quasar
It is an exotic and distant object, which has a velocity of recession of approximately 270,000 kilometers per second (!) or - 91 percent of the
velocity of light itself.
The results show that this quasar, known as Q1442+101, is among exotic objects receding from the Milky Way at tremendous velocities of thousands
and occasionally even hundreds of thousands of kilometers per second!
20,000-Solar-Mass Black Hole Found At The Core Of A Now-Destroyed Dwarf Galaxy
The formation of stellar-mass black holes through the collapse of massive stars is well accepted. However,
it is not yet completely clear how the supermassive objects are formed.
They may form through the merger of smaller, intermediate-mass black holes (IMBHs) weighing hundreds to thousands of suns.
Unusual Pulsar Or Alien Signals?
The pulse timing of this object is considered unusual.
What kind of phenomenon is related to this object?
It is the first time this kind of phenomenon has been observed by astronomers.
The "Cloaked" Star Was Difficult To Find
An object obscured by dust, and buried in a two-star system enshrouded by dense gas, is not easy to find.
A "cloaked" star was discovered after it ate a little of its neighbor. The meal must have given the star a bit of indigestion, because it
"burped" with a blast of high-energy radiation, which gave it away.
Black Gaps In The Sky Puzzle Astronomers
Very dark isolated interstellar clouds of very cold gas like black gaps have puzzled astronomers for more than a century.
Looking at the sky in the direction of the constellation Sagittarius, it is clear that there are extremely dark,
opaque knots of gas and dust especially in the region toward the center of our Milky Way.
Invader From Another Galaxy
This alien intruder from another galaxy is in many ways different from other exoplanets observed by astronomers.
Located about 2000 light-years from Earth in the southern constellation of Fornax (the Furnace), the Jupiter-like planet orbits a dying star of
extragalactic origin and risks to be engulfed by it.
Intimate Connection Between Black Holes And New-Born Stars
Astronomers have known for some time that black holes and
supermassive black holes
accretion and star formation appear intimately connected.
However, it does not mean that powerful gravitational forces of the black holes disrupt surrounding material in their vicinity.
Power To See Most Distant Objects In The Universe
The 3C294, is one of the most distant galaxies recorded by Chandra, the most sophisticated X-ray observatory ever built.
The cluster 3C294 is even 40 percent farther (!) than the next most distant x-ray galaxy cluster.
Chandra focus on X-rays from high-energy regions of the Universe and see the invisible.
It is so sensitive that it can capture images of particles as they disappear into a black hole deep in outer space.
