A team of researchers from the University of Zaragoza, King's College London and the Institute of Astronomy in the UK, led by Ciaran O'Hare, found a collection of stars that were all moving in the same direction. They called this the S1 stream, and these stars are believed to be the remnants of a dwarf galaxy that was swallowed by the Milky Way, billions of years ago.
You may or may not have read the news about the asteroids that flew extremely close to the Earth over the last few days (November 9-10, 2018). These bodies were believed to be as big as houses, and therefore, there was a compelling reason to worry that they may encroach on our atmosphere or something similar. However, most of these scary super-close space missiles are not capable of harming us at all.
For a long time it was suspected, but now there is solid evidence, via a set of images, that the supermassive black hole (SMBH) — dubbed Sagittarius A* and pronounced A star — is present in our galaxy's midst. Previous research calculated that this ‘monster’ black hole could be about 4 million times the mass of the Earth’s sun and located about 25,000 light-years away from our planet.
Remember when Tesla blasted one of its cars into space? SpaceX, which, like Tesla, is owned by billionaire entrepreneur Elon Musk, performed this stunt in February 2018. This was done to raise awareness of the company’s plans for crewed missions to destinations like Mars. Also, there was room in the payload of an unmanned launch that was scheduled for February 6, 2018.
Recently, the National Aeronautical and Space Administration (NASA) had a bit of a mystery to solve. Its deep-space telescope, Kepler, had gone to sleep unexpectedly, and its operators could not get it to wake up or respond again. This unscheduled move by the craft was reported by NASA on October 19, 2018.
Since 2007, scientists have detected 22 fast radio bursts (FRBs), a type of super-high-energy signal from space. The problem is that they have no idea what the signals are or from where they are originating. Now that more activity is being discovered from outer space, it has only deepened the mystery further.
Over the years, numerous theories from the world of physics and astrophysics have informed the popular perception that black holes function to engulf the luckless particles that venture too close to them, out in space. Some of these theories suggest that this matter will never re-emerge from the dark body, and they have effectively been sucked out of existence. Other hypotheses, however, indicate that certain particles may contribute to the ‘jets’ that black holes appear to spew out from time to time. These jets deliver huge bursts of radiation such as X-rays.
In 1967, Professor Wheeler introduced the term "black hole" to the world. They are believed to be massive bodies (regions or stars), small in size and a powerful gravitational field from which even light cannot escape.
A US astronaut and a Russian cosmonaut were forced to make an emergency landing after their Russian Soyuz rocket malfunctioned on the way to the International Space Station (ISS).
Curiosity is a set of scientific instruments mounted on a robot much like a car. It is currently located in the Gale crater on the surface of Mars. Curiosity has been on the red planet for seven years now, looking for signs of life or the potential for it. This mission has not always gone smoothly for NASA, who sent Curiosity to the crater in 2011. It has faced some technical issues and has not been able to send vital data back to the space science organization.
Last week, the Hubble telescope stood down from observing and put itself into “safe mode” after one of its gyroscopes, which keeps it aimed at objects of scientific interest in space, died.
On Sunday, October 7th, at 7:21 p.m. PDT, SpaceX successfully launched the SAOCOM 1A satellite from Space Launch Complex 4E (SLC-4E) at Vandenberg Air Force Base in California. The satellite was deployed about 12 minutes after liftoff.
Stau Sleptons: The Bizarre Particles Blasting Out Of Antarctica And Changing The Face Of Modern Physics
Physicists have detected something mysterious coming from Antarctica’s frozen ground, a sort of cosmic ray - a light energy particle that has blasted its way through space, into the Earth.
“If aliens ever visit us, I think the outcome would be much as when Christopher Columbus first landed in America, which didn't turn out very well for the Native Americans.” - Stephen Hawking
There are a growing number of companies, and their investors, who believe that the time for consumer-grade space flights are upon us. For example, Elon Musk’s interstellar-focused business, SpaceX, has put all of its weight behind its newest and biggest rockets for planned off-world launches. Obviously, these journeys may not be able to go much further than Earth’s orbit at this point. Nevertheless, SpaceX is reportedly attracting paying customers to reach these destinations.
As a planet, Saturn is perceived as swathed in softly-colored clouds, possibly in bands of an extremely fuzzy definition that surrounds the planet in uniform hooped bands. However, astronomers and astrophysics have been aware of an odd anomaly within these clouds. It exists near the planet’s northern pole and has notably pointed corners, not seen elsewhere on the planet. As there are six of these intersections, the anomaly resembles a hexagon. Despite its remarkable incongruity with the rest of the planet, the shape has been observed reproducibly in papers and reports since the 1980s.
It was Neil Armstrong who, after stepping on the moon, said, “That’s one small step for man, one giant leap for mankind.” But it definitely seems as though modern-day science and the researchers of today have already achieved goals bigger than ever imagined!
Astrophysicists have concluded that the history of Earth and its bodies was written in fragments of the asteroids that were in the same area at the time. Those objects may bear the ‘scars’ of the sun’s actions during this period. Subsequently, some of these asteroids crashed into Earth. They form a convenient source of information that allow humans to infer plausible narratives as to what went on in the solar system during its infancy.
Just over 400 years ago, two stars in our galaxy collided in space. This event was observed by astronomers on Earth, although they were not able to detect all the spectacular details and fallout of this event.
