436 b(sometimes known as gj 436b) is a Neptune-sized planet that orbits a red dwarf known as Gliese 436, a star that is cooler, smaller, and less luminous than the Sun. Located approximately 30 light-years from Earth towards the constellation of Leo.The planet completes one full orbit around its parent star in just a little over 2 days. This short orbital period indicates that the planet is located remarkably close to its star. According to NASA, the planet has more than 7,000 times less methane than it should, and it has a surprising abundance of carbon monoxide molecules. And therein lies the second mystery carbon monoxide should not be present to this degree, as it becomes scarce when temperatures soar above a certain threshold. As Astronaut reports, Carbon, when it is cold, likes to hold onto hydrogen, but if it is hotter it likes to throw off the the hydrogen and steal oxygen from, say, water molecules, to make carbon monoxide. This strange ice substance can remain solid despite blisteringly hot temperatures we are talking so hot, it could literally melt your face off...
B2 Cloud is ten thousands light-years from Earth in the constellation Aquila.the cloud is 1000 times larger than the diameter of our solar system. It contains enough ethyl alcohol to fill 400 trillion trillion pints of beer. To down that much alcohol, every person on earth would have to drink 300,000 pints each day for one billion years. The cloud contains ethyl formate, an ester that helps give raspberries their taste and reportedly smells like rum. It seems, then, that the center of our galaxy may taste and smell like raspberry flavored rum. If you're thinking of getting free alcohol for life think again.Sadly, for those of you planning an interstellar pub crawl, the cloud is 58 quadrillion miles away. It is also a cocktail of 32 compounds, some of them as nasty as carbon monoxide, hydrogen cyanide, and ammonia.Most of it’s undrinkable, though. The cloud holds mostly methanol, the same alcohol in antifreeze and windshield washer fluid.
CMB(Comsic Microwave background), was created about 400,000 years after the Big Bang, the expanding universe began to cool down, and atoms were created. The universe used to emit an orange light, but after this cool down period, the light turned into microwaves. The CMB is pretty uniform across the universe, with a few small fluctuations here and there. But scientists have discovered one major cold spot that's so far inexplicable. There are a few theories as to why it exists. It could be that it is surrounded by supervoids, huge areas of space that have nothing in them, which causes the CMB waves to "cool down" as they pass through, as there's no gravity in those areas to energize them.
Discovered in 2015, J0100+2802. The largest black hole in the universe inside the largest Quasar, with the highest luminosity of any known quasar. It formed only 900 million years after the Big Bang, and should not be anywhere near the size it is for its age. A quasar is an extremely bright cloud of material in the process of being sucked into a black hole. As the material accelerates towards the black hole it heats up, emitting an extraordinary amount of light which actually pushes away material falling behind it. This process, known as radiation pressure, is thought to limit the growth rate of black holes.
A star named KIC 8462852, aka Tabby's Star, kept dimming. As though something was passing in front of it. Since then, scientists have been trying to figure out what that something might be. A swarm of comets flying by, en masse? An alien megastructure? Then, in 2019, a team of astrophysicists proposed a new, more plausible explanation. There are really two mysteries centered on Tabby's Star. First, the star keeps brightening and dimming in a bizarrely sporadic pattern. While very young stars will occasionally behave like this astronomers have never seen it in a star of Tabby's age. Second, the star is slowly, but surely, getting dimmer over time in a steady decline that astronomers have never observed in another star of its type. If aliens built a megastructure called a Dyson Sphere to siphon off the star's energy that could explain how the star is a whopping 10% dimmer than it was just a century ago. Astronomical Society that argued for a different culprit: The dusty remains of a dying moon. According to Metzger's models, a gas giant may have orbited the star millions of years ago. And like Jupiter and other gas giants, it hosted a few icy moons. It's unlike an alien machine, we see moons all the time.So, mystery solved? Not quite. Astronomical Society still have more research ahead of them.
