Fast Radio Bursts Are Astronomy's Next Big Thing

Anna’s typical workday would last from 3:00 P.M. to 6:00 A.M. As part of her observation preparation, she would visit with the observatory staff to discuss new findings and review what has taken place since her last visit. She stars by pulling out a list of dwarf galaxy stars, ordered by priority. She chooses the first star and asks the operator to move the telescope into position so that she can begin collecting starlight data. The article states that her research primary focuses on stars in ultrafaint dwarf galaxies. This article goes onto discuss that after the big bang, the first stars were formed from gaseous clouds. We know the big bang to be when the universe

As more complex telescopes are being created, scientists can get closer to observing the formation of early galaxies. In visual observation, redshift now comes into play. Edwin Hubble discovered in the 1920s that the light of far away galaxies have a wavelength that has been

Images of the galaxy in the radio portion of the electromagnetic spectrum show two jets protruding in opposite directions from the galaxy's center. These jets extend many times the width of the portion of the host galaxy which emits radiation at visible wavelengths.[5] At the ends of the jets are two lobes with "hot spots" of more intense radiation at their edges. These hot spots are formed when material from the jets collides with the surrounding intergalactic medium.[6]

Shapely pointed out that the brightnesses and colours that had been measured in spiral nebulae were different compared to what he would expect to see if the Milky Way was observed from a distance. He suggested that the nebulae were, somehow, completely different to our Milky Way. To this, Curtis had no reply. Today we know that the differences exist because of interstellar absorption and reddening, which stops astronomers from looking at our own galaxy to compare it, but none of this information was known at their time. Curtis also noticed that the spectral lines seen in spiral nebulae were normally the same, with the nebulae’s being groups together huge amounts of stars. This was right, and supported his argument about there being stellar systems similar to our own

“Active galactic nuclei” are objects occupying the center of many galaxies that consist of an accreting supermassive black hole and are some of the most luminous and powerful bodies in our known Universe. In the galactic-BH accretion process, gaseous matter from the galaxy is pulled into the black hole and is converted to into radiation that is then released radially outward into the host galaxy. Due to the rapid-fire accretion onto the Supermassive Black Hole, Active Galactic Nuclei (AGN) can emit radiation into their host galaxies that span much of the electromagnetic spectrum from X-rays, IR, UV, and radio waves. Researchers have organized AGN into groups based on their

The astronomers studied the elliptical galaxy M87, located 53 million light-years from Earth in the constellation Virgo. They examined a unique series of images taken with the Hubble Space Telescope over the course of three months in 2006. They quickly found what they were looking for.

The Gamma-Ray Spectrometer or GRS instrument had three detector systems that measured the spectra of flare X-rays and gamma rays which showed that gamma ray emission from even modest flares was common and that particles are accelerated in flares to high energies in just a few

NASA's Hubble Telescope has seemingly maxed out. Recently, an international group of astronomers have measured the distance to the most remote galaxy ever observed. It what is known as GN-Z11, this galaxy is one of the first galaxies to form. Its existence can be traced as early as 400 million years after the Big Bang. Knowing this brings astronomers one step closer to finding out how to the universe was created. In other words, they may have just found God.

Have you ever wondered how it would feel to experience life on a space mission? Now you have the opportunity to have gravity pull you in and to come along through a journey into space on Galaxy Impact! You’ll be faced with top speeds of 75 miles per hour with an overall time of 60 seconds on Galaxy Impact. This ride features the newest technology including several virtual reality screens; therefore, simulating an incredibly real scenario. Jump onto our surround sound cars that hold 32 people at a time. In these inverted seats you’ll be able to pull the harness over and down until it can’t possibly continue any further, and as a result, you’ll be immaculately secure. With the design of these cars, you will feel as if you are floating

This discovery was awarded to the former teacher and student because as the pair was searching systematically for pulsars. Russell A. Hulse and Joseph H. Taylor using the 300-m radio telescope at Arecibo, Puerto Rico. They discovered a pulsar which is a rapidly spinning neuron star emitting radio pulses at intervals that varied in a regular pattern, decreasing and increasing over and eight hour period. While Hulse observing the new pulsar, which was named PSR1913+16, he found that the pulses are often noticeable more than other times. During the observation of shifts in the pulses they found that the stars were equally heavy. A pulsar is a rotating neutron star that produces signals in earth detectors as its beam of radiation sweeps over earth once per rotation. The binary pulsar which is what was discovered has period of 59 milliseconds but shows an orbital period of seven hours and 45

In space discovery history there have been many findings and observations. Through extensive space travel we have learned more about our universe than we did before. In the early and late part of the 60’s several scientific discoveries were made.

These jets were detected by the Karl G. Jansky VLA by radio observation. Thereafter the dwarfs were observed by different telescopes in order to confirm this as a real finding and not a fluke.

The first hypothesis is the nebular hypothesis. This hypothesis starts with a giant, spinning cloud

Our X-ray sample consists of 124,730 objects from the combination of \textit{ROSAT} All-Sky Survey (RASS) Bright Source Catalog (rass-bsc) and RASS Faint Source Catalog (rass-fsc). RASS is the first all-sky survey in soft X-rays (0.1-2.4 keV), conducted in 1990/91 with ROSAT, a German X-ray telescope satellite~\citep{1999Voges}. The reason that we start the survey with an X-ray catalog is because all galaxy clusters are bright in X-ray from their hot ICM and a central QSO. \corr{We include the bright source catalog because distant cool cores may look like point sources. In addition, according to~\citet{2002Cruddace}, a flux limit for \textit{RASS} for clusters is $3\times10^{-12}\,\rm{erg/s}$, corresponding to $L_{x}=10^{45}\,\rm{erg/s}$ at $z=0.5$.}
