The Milky Way might just be a galaxy, but a study shows that it has about 100 million black holes. "The researchers looked at the properties of starts and galaxies" in order to estimate the amount of black holes the Milky Way had. Daniel Holz, a physicist, said that 100 million may sound like a lot, but it's actually small (based on "astronomical standards."). The Milky Way has many, stellar-mass black holes. They are formed when "massive stars collapse". To conclude, there may be millions of black holes in the Milky Way, but it's nothing to fear. | The Milky Way might just be a galaxy, but a study shows that it has about 100 million black holes.

Gravitational Wave Detectors that Could be Used to Find Exoplanets in the Future
The launch of the LISA mission could be a very important part of possibly finding exoplanets. LISA can detect gravitational waves and it could somehow hear gravitational waves from some exoplanets system. If LISA turned out to be very good, it could reach the Milky Way and/or farther. LISA could find hundreds to thousands of whit dwarf binaries. This could help with finding new worlds. However, there is not a possibility that the worlds found would have life on it. Overall, LISA could be somewhat successful in finding exoplanets. Source: https://www.scientificamerican.com/article/future-gravitational-wave-detectors-could-find-exoplanets-
Noctilucent Clouds
Noctilucent clouds are very rare clouds. They have a blue color because they are near the ozone layer,which absorbs all the red light and lets out the blue light. Normally, the clouds would be located on the mesosphere, but every year, since 2002, they have been slowly getting closer. The ripples or waves on the clouds are from “atmospheric gravity waves.” If it weren’t for the clouds, then they would appear invisible. To conclude, noctilucent clouds aren’t clouds that you would always see, but you never know, if it's the right time and place, you might get a chance.

Pets can also donate Blood

Cats and dogs react differently to the blood. If a cat is given the wrong blood, then they can have a "deadly reaction". But, a dog can receive any blood type.
