Scream in the Space, Not a good idea
The experiment took place at Brunel University London in which they sent a speaker and microphone on a satellite to near-space to examine how high-up the scream could yet be heard. Noha from South Africa proposed the organization to send a recording of her calling her kids with a scream of “Children! Come and clean your room.” The claim that no one can hear you scream in space was authenticated by this experiment. This event alluded in 1979 sci-fi horror Alien. As the altitude increases and the air becomes rarer, the level of the sound picked up by the mike should decline.

Universe’s Expansion – A Mystery
A new measurement has been made by researchers focusing on an essential question, “How fast the universe is expanding,” using a completely distinctive kind of endeavor. The updated analysis, which originates from NASA’s Hubble Telescope, may lead to a new understanding of the universe’s fundamental characteristics. What does this expansion mean? The distance b/w galaxies across the universe are becoming ever more widespread, and how quickly space is stretching is given by the Hubble constant. As the research objects to more and more discrepancies b/w predictions and the observations, scientists are considering whether they may require to come up with a new theory/model to encounter this problem.
Nice to not see you
Asteroid QV89 was found for the first time in August 2006 and was observed only for only ten days. It is a tiny object 20 to 50 meters in diameter, having chances of 1-in-7000 of striking our homeland “the Earth” this September. European Southern Observatory (ESO) and collaborators precisely determined on 4 and 5 July that we will not be going to see this asteroid harming the Earth anytime soon.
Aliens on the earth? – Area 51
Area 51—in Southern Nevada is a secretive military area conceived for the conspiracy that they are hiding evidence of a crashed UFOs & aliens. A trend is seen in the previous month on social media in which people intended to raid the area-51, and more than a million people signed up for this. It never happened as the military put up a warning against it.
“The forbidden aspect of Area 51 is what makes people want to know what’s there,” says Peter Merlin who has been researching on area-51 for more than three decades.
Based on pictures shown by Google Earth, the area is still active as new development and expansions are continuously occurring. So something might be there, who knows?
