Astronomers Discover 'Monster Exoplanet' Which Shouldn't Exist — but Does
Exoplanets have been found in all different types and sizes, showing how much diversity there is among planets outside of our own Solar System. Now another one, a "monster exoplanet," is of interest to astronomers because according to current models of planetary formation, it shouldn't exist — but does.
What Was the Solar System's Mysterious Interstellar Visitor Last Week?
Last week, something unusual was detected moving through the Solar System, a small object which didn't seem to behave like any known comets or asteroids. In fact, its behaviour suggested that it originated from outside of our Solar System. So what was this mystery interloper? While not 100 percent identified yet, it seems to be an interstellar asteroid or some similar rocky body.
The Kardashev Scale
Nikolai Kardashev is a little known Russian astrophysicist—certainly in regards to the current phenomena of science-related pop-culture icons, but despite this, some of his ideas have seeped in through the cracks. If the layman recognises his name at all, it won't be for the work that he put into examining the quasar CTA-102, but for the more theoretical exercise of developing what we now know as the Kardashev Scale. Even if you're not familiar with its name, there's a chance that you'll know a bit about its substance: Nikolai proposed the idea that some galactic civilisations would be possibly millions—even billions—of years ahead of us in regards to technology, and developed a scale in order to help with the categorisation of any civilisations that we may come across, or possibly fit into ourselves.
Astronomers Strike Gold (Literally) in the First Observations of Gravitational Waves Produced by Colliding Neutron Stars
There was some big astronomy news this week, as astronomers announced the first direct observation of gravitational waves produced by the collision, or merging, of two neutron stars. This collision even produced some heavy elements, such as gold. It sounds like science fiction, but is very real. Gravitational waves have been seen before, but those ones were caused by the collision of two black holes. This was also the first time that such an event (known as GW170817 in this case) had been detected in both visible light and gravitational waves.
Us Humans Are Too Curious for Our Own Good
When the New Horizons space probe launched in 2007 I couldn’t wait for it to reach Pluto in 2015 and finally reveal many secrets of that mysterious dwarf planet. Once that time came I was fascinated to read about the physical details of Pluto that had never been seen before, such as Pluto giving off x-rays. I experience the exact same curiosity whenever a new extrasolar planet is discovered, as well as distant quasars (almost as old as the universe itself).
Under Metallic Skies: Titanium Oxide Discovered on Exoplanet For First Time
Space telescopes and ground-based telescopes have been discovering a wide variety of exoplanets in the last few decades - several thousand have been found so far and the estimated total number is in the billions in our galaxy alone. Now, astronomers have found the first exoplanet with titanium oxide in its atmosphere. The chemical compound is rare on Earth but can be found in the atmosphere of some cooler stars.
NASA Says Good-Bye to the Cassini Saturn Orbiter
On September 15, 2017, the Cassini-Huygens mission to Saturn will culminate in a dramatic and fiery collision with the planet's upper atmosphere. NASA, the European Space Agency, and the Italian Space Agency teamed up for the groundbreaking mission that has changed what we know about planetary science and space travel itself.
Astronomers Detect 15 New Enigmatic Radio Bursts from Distant Galaxy
In the search for extraterrestrial intelligence, astronomers have come across a variety of unusual phenomena in the universe; while natural explanations have been found for them, so far at least, some of these phenomena can be very bizarre. Fast Radio Bursts (FRBs) are one such example, and one for which an explanation has not yet been found—very brief (milliseconds), but powerful radio emissions from outside of our galaxy. Now, a new detection of 15 repeating radio bursts has been made by astronomers, adding a new piece to the puzzle and posing more questions.
Are There Wormholes at the Black Holes' Core?
What happens when you remove the singularity from a black hole? A wormhole might appear right in the center of it. Can you go through, can we travel through time? Nobody knows for sure, but in case you are immensely bold, the easiest way to find out is diving right into it.
We've Just Discovered that Martian Nights See Snowstorms
Space. The final frontier. It just got a little more interesting. Here's why: We Now Know, Theoretically, That Mars Gets Snowstorms. And They're Not Much Different Than What We Experience Here on Earth.Pierre Roustan, Author of THE CAIN LETTERS and SCARY HORROR STUFF!
Cosmic Rain: NASA Launches New Experiment
NASA's Cosmic Ray Energetics And Mass for the International Space Station, aka ISS-CREAM, got underway August 14, 2017 by hitching a ride to the ISS with the SpaceX Dragon rocket in a successful launch. CREAM will be installed in Kibo, the Japanese Experiment Module Exposed Facility. The experiment is designed to probe the mysteries of cosmic rays, or cosmic rain.
On-Demand Spaceship Parts from Pink Goop?
One of the most fascinating technologies to be birthed out of the turn of the millennium is additive, or 3D, printing. And like many other scientific discoveries and inventions, it doesn’t take a ton of imagination to see how something like that might be useful in space. In fact, I would argue that in order for something like a colony/generation ship to be successful, it would absolutely need to have the ability to manufacture new parts on the spot.
