Milky way
The Milky Way is a huge collection of several hundred billion stars, dust, and gas. It is a spiral galaxy that is about 13.6 billion years old. The Milky Way is the galaxy that includes our Solar System. The Solar System is located at a radius of about 27,000 light-years from the galaxy’s center. The galaxy is rotating, and it takes us about 240 million years to complete one circle around its middle.
Magnetic field controls the material’s movement around the black hole
Using observational data from the Stratospheric Observatory for Infrared Astronomy (SOFIA), astronomers recently discovered that the magnetic field near our galaxy's core is so...
Milky Way’s black hole unleashed enormous outburst about 3.5 million years ago
A supermassive black hole in the center of the Milky Way galaxy exploded an enormous outburst almost 3.5 million years ago. The black hole,...
The halo surrounding the Milky Way is much hotter than previously thought
The outer "halo" region of the Milky Way, as with other galaxies, contains the vast majority of the mass of the Galaxy. Yet the...
Astronomers captured a super-rare type of galaxy
Astronomers have seen a very curious object that they never saw before. They recently captured an image of a super-rare type of galaxy named...
Galactic collision may have triggered Solar System formation
The formation of the Solar System has puzzled scientists for centuries.
Now, it seems that scientists have finally known what causes the solar system's emergence.
According...
ALMA detected twinkling heart of the milky way
Sgr A* sometimes flares up in millimeter wavelength. Now, for the first time, astronomers obtained high-quality data of radio-wave intensity variation of Sgr A*...
A massive rotating disk found in the early universe
Atacama Large Millimeter/submillimeter Array (ALMA) discovered a massive rotating disk galaxy when the universe was only ten percent of its current age, challenges the...
Scientists discovered one of the oldest objects in the Milky Way
A new study has focused on the spectra of NGC 6652 obtained by the Cerro Tololo Observatory and found that the globular cluster NGC...
Milky Way may have 100 faint satellite galaxies
In our solar system, planets have their satellites. Like those, our galaxy has its satellite galaxies, and some of those might have smaller satellite...
We live in a halo of dark matter, study
Scientists cannot directly observe dark matter, but they know it exists by the way it exerts a gravitational pull on other matter. Dark Matter...
Astronomers investigated a luminous supernova remnant (SNR) W49B
Studying Supernova Remnants is essential to better comprehend their role in the evolution of galaxies, dispersing the heavy elements made in the supernova explosion...
Astronomers witnessed most energetic outflows ever in the universe
Using the unique capabilities of NASA's Hubble Space Telescope, astronomers observed most energetic outflows ever releasing from quasars and tear across interstellar space like...
