According to a team of Canada-based scientists, the Milky Way weighs between 400 to 580 billion solar masses (or 4.0 X 1011 and 5.8 X 1011 solar masses). The sun's mass is two nonillion kilograms times the Earth's mass.
According to a study in the UK, the spread of cancer-causing tumors can be cut by as much as 75 percent by altering the immune system. Using genetically modified mice for the experiment, scientists identified a total of 23 genes involved in regulating the spread of cancers. Targeting one of these genes, called Spns2, led to a three-quarter reduction in the spread of the tumor.
Iridium Communications Inc. has successfully launched its first ten Iridium NEXT satellites. Delivered into low-Earth orbit approximately one hour after being launched by a SpaceX Falcon 9 rocket, the satellites are part of the company's next-generation satellite constellation sent to replace and enhance its existing network of low-Earth orbit satellites spanning the entire globe.
Planet Nine seems to be more mysterious than first thought. This elusive world, which has been suggested to be hiding beyond the orbit of Neptune, has been described as a "rogue planet" that was part of our solar system in the past.
How long has the moon been shining on Earth? Astronomers from the University of California, Los Angeles, have determined how old is our moon, estimating it to be 140 million years older than first thought. This would mean that the moon may be as old as 4.51 billion years old.
Astronomers may finally have the answer to why the mysterious, famous "alien megastructure star" (or Tabby's Star) is behaving like no other. Apparently, this star may have devoured an entire planet, causing its weird behavior.
Austrian physicists have created negatively charged hydrogen clusters, a previously unseen form of hydrogen. The existence of hydrogen in ion clusters has been known for the past forty years, and positively-charged clusters have already existed. But by injecting cold liquid helium droplets with hydrogen before exposing it to an electron beam, the researchers created negatively charged hydrogen ions.
SpaceX successfully launched its first space mission on Saturday by sending a fleet of communication satellites into orbit. More importantly, its unmanned reusable rocket returned and landed on a floating robotic platform across the Pacific Ocean.
A rare ruby seadragon has been captured alive on camera for the first time. The ruby seadragon was identified as a separate species in 2015. The video recording shows two ruby seadragons for about 30 minutes. The footage is expected to help the scientists gather more information about the sea creature.
Despite ultramodern technology, scientists had incorrectly estimated the age of the moon. A new study has revealed that the moon is about 4.51 billion years old.
