We should be worried about being wiped out by a killer pathogen that is specifically designed to kill people of only a particular race, based on their DNA, warns scientists.

A new report from Cambridge University's Centre for the Study of Existential Risk says that world ogvernments have failed when it comes to preparing against threats like futuristic bioweapons powered by AI and genetic manipulation. Such weapons would have to power to target specific DNA, and kill certain races of people leaving other swaths of the population unharmed.

Imagine it being sprayed in the form of the tinfoil hat conspiracy of chemtrails, and wiping out certain portions of the population.

Planetary scientists have estimated that at some time in the extremely distant past that a planetary embryo collided with Jupiter's core, disrupting its development process.

A new report has been published in the Nature's International Journal of Science, this report shines a new light on the past events of Jupiter's formation. According to the paper, scientists are now giving educated guesses towards a planetary embryo once having a head-on collision with an early stage of Jupiter's core. The paper says that since the Juno mission (a space probe sent out to observe Jupiter) has returned recent data, the once assumptions of Jupiter's core structure and gravitational fields have changed.

The new data sent back from Juno also indicated that Jupiter's core composition had a change throughout its development, scientists estimate that this was caused by the colliding planetary embryo. Scientists ran a simulation with this new found data, the simulation consisted of this embryo planet colliding with Jupiter's core and mixing its heavy elements into Jupiter's inner envelope, resulting in a diluted core. The simulation findings were representative of Jupiter's core. The same scientists expect that Jupiter isn't unique in this regard, as they say that Saturn could have experienced similar events.

NASA will be allowing the private Dream Chase space plane to hitch a ride on their new Vulcan Centaur rocket to the International Space Station (ISS).

According to a new announcement out of the Sierra Nevada Corp, their space shuttle-like vessel that resembles much like a plane, is scheduled to launch with the new Vulcan Centaur rocket that's headed to the ISS. Dream Chaser will be transporting more than 12,000 lbs (5,400kg) of cargo to the space station over the course of six mission, the first of which will begin in late 2021.

ULA Chief Executive Tory Bruno told reporters that "I have been a fan and a supporter and a cheerleader of this amazing vehicle from the first moment I saw it. To be able to make Vulcan's commercial debut with this block of missions underneath the Dream Chaser is just truly exciting." The first test flight is scheduled to begin in 2021, and if the Vulcan Centaur rocket isn't ready to launch by then, Bruno has said that they can always fall back on the already prepared Atlas V. "We're on time with Vulcan, but if something should arise, we're going to make sure that you fly when you're ready."

NASA has said that they will discussing their agency's plans for how astronauts will be landing on the Moon by 2024 on August 16th.

NASA Administrator Jim Bridenstine accompanied by U.S. Representatives Mo Brooks, Robert Aderholt, Scott DesJarlais and Brian Babin will be revealing the agency's plans for getting humans back on the Moon by 2024 through their Artemis program. The discussion will revolve around how NASA plans to safely land on the lunar surface, and questions and answers will be provided after the initial announcements.

NASA plan on getting the first women and the next man on the Moon in just five years time, this will be done through the Artemis program which is detailed here. Tune into the discussion on Friday, August 16th for more space information. If you didn't know, NASA just completed the final and most complex part of their Orion spacecraft, check that out here.

Scientists have observed a recent neutron star phenomenon and have deemed it a 'glitch'. It seems that computers and technology aren't the only things that can freak out for no apparent reason.

Researchers who published a paper in the Nature Astronomy journal observed a neutron star called Vela glitching out for a short period of time. For those that don't know, neutron stars a fast-spinning corpses of once giant stars, they harbor about 1.5 times the mass of the sun and are much smaller in diameter. These stars are known to "glitch" out every now and again, this 'glitching' causes the star to slow down its rotation speed, then speed it up and then return back to normal speed.

According to the paper, Vela's normal spin speed is 11 times per second but in 2016 it was caught speeding up. Researchers discovered that Vela's spin has three phases, the first being the slowing down of the spin speed, then the speeding up phase and then a return to its normal speed. Researchers have also tried to determine the components that cause these three phases to occur and ultimately the "glitch" to happen. The components are: a crust of ions connected in a lattice pattern, a roiling "soup" of neutrons inside the stars inner crust and a extremely dense core consisting of protons, neutrons and more particles.

For those that don't know, at the center of our Milky Way galaxy lies a black hole which we have named Sagittarius A. That black hole just had a strange anomaly that caused its brightness to spike 75 times more than normal.

The infrared flaring seen by astronomers is nothing like they have seen before, and astronomers have been observing Sagittarius A for about 20 years now. Astronomers used the Keck Telescope to observe the flaring and according to the scientists this flaring occurred for about 2.5 hours. At first, astronomers thought the flaring was caused by the neighboring star SO-2 which has an elliptical orbit close to the black hole, but that hasn't been confirmed.

An interview was held with ScienceAlert with astronomer Tuan Do, he said "The black hole was so bright I at first mistook it for the star S0-2, because I had never seen Sgr A* that bright. Over the next few frames, though, it was clear the source was variable and had to be the black hole. I knew almost right away there was probably something interesting going on with the black hole." At the moment scientists cannot pinpoint what has caused Sagittarius A to flare like this, further research will have to be conducted before a definitive answer can be provided.

NASA scientists have finally captured the first viewings of something they have been searching for years, solar 'Interplanetary Shock'.

NASA launched their Magnetospheric Multiscale mission back in 2015, the goal of the mission was to observe and study how the Sun's solar winds impact the Earth's magnetic fields. In January 2018, NASA scientists managed to capture this space phenomenon using the four launched spacecrafts, this phenomenon was an interplanetary shock.

An interplanetary shock is the transferring of solar energy (solar wind), this phenomenon occurs when a faster patch of solar wind overtakes a slower patch, resulting in the previously mentioned energy transfer, or 'shock'. Since a first time recording of this transfer has now been captured and saved, scientists hope that with this new information that they will be able to develop a better understanding of how it all works, while also hoping to be able to capture other space phenomena.

Astronomers have stumbled across a brand new black hole discovery that has shocked and stunned scientists at the sheer size of what they have witnessing.

Astronomers have discovered a black hole sitting at the center of a super-giant elliptical galaxy called Holmberg 115A which is located about 700 million light years away. The black hole that is sitting at the center of this galaxy isn't the standard black hole, its actually about 40 billion times the mass of our Sun and has been observed by astronomers in Chile with the Very Large Telescope.

To put into perspective how big 40 billion times the mass of our Sun is, if this black hole was positioned where our Sun is now (at the center of our solar system) then its size would stretch out past Neptune and Pluto and into interstellar space. According to authors in the published paper, this black hole is "four to nine times larger than expected given the galaxy's bulge stellar mass and the galaxy's stellar velocity dispersion."

Jupiter is simply massive and due to its size and gravitational pull a meteor has collided with the planet and the explosion was so big it was viewed from Earth.

Since Jupiter is so big, it's gravitational pull captures a lot of space debris including meteors that are abundantly floating around space. Astronomer, Ethan Chappel going under the guise of Chappel Astro on Twitter viewed the impact of the meteor and said "Today has felt completely unreal to me. Hoping someone else also recorded the impact to seal the deal."

Another group of astronomers estimated the meteors size, saying that the object was 16.5 feet to 65 feet in diameter and that meteors of this calibre collide with Jupiter between one and five times a month. Above we have a gif of the collision and we can see the impact in the bottom left hand corner of the gif. If you happened to miss last weeks news regarding Jupiter, the Hubble Space Telescope took the best image we have of Jupiter now, check that out here.

Last week a video spread across social media of an explosion at a military facility, something that I saw myself but didn't have the time to sit down and write about it until now. First off, check out the video below which shows some pretty crazy stuff:

When I sat down to write this story I noticed it had been picked up by other media outlets, so I checked them all to see if they were showing the actual video of the explosion or simply reporting on it. Well, all I got were reports which make it seem much less severe than the video itself does. None of them have the video embedded.

Authorities have confirmed that the mysterious explosion at the Russian weapons testing range "involved radioactive materials". Rosatom, Russia's nuclear energy company, said in a statement on August 10 that five employees had died along with two military personnel.
