Hello, space fans! I am excited to host the Carnival of Space episode 577. If you’re new to this weekly curation of handcrafted space stories then let me explain. Every week a space journalist hosts the Carnival of Space and posts all the amazing posts from other space advocates in the community. It’s something UniverseToday started and has been going for years!

Alright, let’s jump into the good stuff.

 

Universe Today – Look at all the Aerosols Pushed into the Atmosphere, from Fires, Volcanoes and Pollution. Even Sea Salt Thrown into the Air from Hurricanes

Here’s a great article on NASA’s visualization of aerosols. It shows where aerosols aggregate in the atmosphere. What’s fascinating is the annotations that NASA put on this visualization. UniverseToday highlights these insightful features and dives a little deeper to understand what it all means. Check out the article here!

 

Universe Today – This is a 3D map of 400,000 Hot Massive Stars Located Within 10,000 Light-Years From the Sun, Thanks to Gaia!

Gaia is an exciting mission launched by the European Space Agency in 2013. What’s amazing about it is that its mission is to map the entire Milky Way and beyond. They released their latest batch on April 25th and astronomers all around the world discovered some amazing finds. Universe Today takes a look at the maps created and what was found from this valuable data. Check out their article here.

 

Universe Today – We’re in the Milky Way’s Second Life. Star Formation was Shut Down for Billions of Years

The Milky Way is believed to have formed shortly after the Big Bang. We also know that our Milky Way has merged with other satellite galaxies on the way. However, a new study led by a team of Japanese astronomers discovered something surprising. They found that there was a time when the Milky Way wasn’t producing as many stars and was actually dormant for a period of time. So much so that the Milky Way was actually dying until it was jump-started again. Read more over at Universe Today here to see what else researchers found.

 

Universe Today – Dust off Your Lunar Colony Plans. There’s Definitely Ice at the Moon’s Poles

All eyes are set on the Moon for the near-future. From new human-rated missions to the Moon from China to the U.S to setting a Moon base as well. However, scientists discovered there may be ice on the Moon which we’ve previously never seen. Check out the full article over at Universe Today here.

Universe Today takes a look a the Cosmic Watch smartphone app. If you love to casually look around the Cosmos and explore the stars then check out this article for what you can expect here!

 

Universe Today – There are so Many Water-Worlds Out There

Scientists uncovered that exo-planets two to four times larger than Earth will likely have water as a main component. Universe Today takes a look at what this all means and what else scientists have dsicovered from this new research. Read the full article here.

Universe Today – Another Way to Search for Biosignatures of Alien Life. The Material Blasted out of Asteroid Impacts

Asteroid impacts can be detrimental to life on any planet. The dinosaurs are a great example of life that truly ruled the world but ended abruptly. One aspect of major destruction events like that is new and old life finds a way to preserve and survive through it. Without that catastrophic event, humans may have never existed. With this in mind, we can look at other exo-planets for asteroid impact material in the atmosphere. Check out Universe Today’s full article here.

 

Universe Today – Lockheed Martin Shows off its new Space Habitat

As we’ve mentioned in previous stories for this week, there is a huge focus on the Moon. If we can set up a habitat and a home base around the Moon then we can get to Mars with that much more experience. Lockheed Martin has teamed up with NASA to build a space habitat. They also have plans to help build one for Mars as well. Let’s go over to Universe Today and check out their full article here!

The Southern African Large Telescope (SALT) is one of the largest telescopes in the world and even the largest in the southern hemisphere. CosmosQuest takes a look at what this telescope can offer and how it’ll help us explore more of the universe. Check out the full article here.

 

CosmoQuest – Above & Beyond – Making Sense of the Universe for 100 Years #IAU2018

A wonderful space exhibition that showcases the greatest astronomy discoveries over the last 100 years. ComosQuest takes a look at how it was displayed as well as some of the initial impressions of this amazing display. This is part of the IAU 2018 conference. Check out their full article here.

 

CosmoQuest – Gruber Cosmology Prize Celebrates the Beginning of the Universe #IAU2018

One of the most exciting discoveries is the map of the universe by detecting and mapping the cosmic microwave background (CMB). During 2009 to 2013 scientists from the European Space Agency Planck Observatory collected data on the CMB. They understood that after the Big Bang the universe was this immensely hot plasma soup that was too hot for individual atoms. Eventually, the universe cooled down after 380,000 years and reached a point of no return where plasma finally collapsed into hydrogen atoms. Guess what’s the most abundant element in the universe and something that even humans are mostly made up of? You guessed it. Hydrogen. As a result of the universe cooling down and eventually producing stars and galaxies it left something behind. It left a faint static signature that was in the microwave wavelength. It literally covered the entire universe. This lay way for scientists to measure this and essentially see the universe’s “baby photo” even after 13.77 billion years later. CosmoQuest celebrates this discovery and looks at what these scientists discovered in more detail and how it impacted our understanding. Read the full article here.

Here’s an interesting and in-depth article about dwarf novae from our friends over at Photon Fishing. Check out the full article here.

 

Photo Fishing – Frosty the Protoplanetary Disk Snowline: Astronomers use methanol to trace the water snowline in a protoplanetary disk

When solar systems like our own form there is a line called the snowline that acts as a divider. The snowline is where gas molecules freeze out onto grains of dust. What Photon Fishing points out that is fascinating is “a planet’s bulk composition is presumably highly dependent on the location of its formation relative to this snowline.” Read the full article to see how the snowline affects the birth of planets and what scientists know about it so far.

Next Big Future – Evidence that Universe has infinite cycle of Big Bangs from very early black holes

CMB

Cosmologists may have found the first evidence that the universe has infinite cycles of the Big Bang. The big indicator is they found old black holes that were evaporating at the beginning of our universe. It may seem that the only probable cause is that these are black holes left over from the previous universe. The theory is called Conformal Cyclic Cosmology (CCC). Read the full article over here at Next Big Future.
