Scientific Discoveries In 2022 Is Mind-Blowing

12 Scientific Discoveries In 2022, scientists have been working so hard during the past months and they have been a lot of achievements.

That’s just a small taste of the great scientific work revealed to the world over the last month and there is so much more happening all the time. Try as we might, it’s hard work keeping up on all the ways the world — and the universe — keeps changing all around us.

Just as soon as we wrap our heads around the latest news, there’s more waiting to be discovered. With that in mind, we’ve gathered up twelve of the coolest stories from the world of science which happened in April 2022 and put them all in one place.

Pluto has ice volcanoes

In 2015, NASA’s New Horizons mission made a flyby of everyone’s favorite dwarf planet, Pluto. It captured the most detailed pictures of the icy world’s surface humanity had ever seen and scientists have spent the past several years scouring the data to uncover what makes Pluto tick.

The reason for T. rex’s stubby arms

T. rex

Scientists have spent decades debating the reason and purpose of T. rex’s arms and have never been able to settle on an acceptable answer. Previous hypotheses suggested that their arms may have been used as pectoral claspers during mating or to push up off of

The ground in the event of a fall. The trouble is that each of those activities would have been better served by larger limbs. No functional explanation explained why they would have evolved to have such puny little grabbers.

A recent paper, however, suggests we may have been thinking about T. rex’s arms all wrong. The new hypothesis centers on the idea that getting smaller was precisely the point.

The birth of a gas giant

By the time evolution got around to making humans, and humans got around to making telescopes, the planets in our solar system were well-formed and mature. When we made our first observations into the cosmos and saw that there were other worlds, like Jupiter and Saturn, we could only see them as they are now.

Battling triceratops

Fenestra in triceratops

Triceratops are famous for their great horns jutting from their faces, and the impressive crests which rise like halos over their heads. Fossil triceratops remains often have holes in their crests, called fenestra, that have interested paleontologists for ages.

It’s been imagined that the holes in their crests might have several causes. Depending on their characteristics, they could be natural formations, or else might be the result of bone loss that comes with age. Another hypothesis involves injury endured during battles with another triceratops.

Mars has two speeds of sound

We tend to think of the speed of sound as being a constant, but even on Earth that isn’t true. Sound travels through different mediums at different rates, such that the speed of sound varies depending on altitude, as a function of atmospheric conditions.

Looking toward other planets, the speed of sound should necessarily be different as a result of the thickness and composition of alien atmospheres. One place we’re able to check that hypothesis is on the surface of Mars, where we have delivered a substantial number of probes and rovers.

Recently, scientists working with the Perseverance rover used onboard microphones to measure the speed of sound on Mars. As expected, the speed of sound was slower, roughly 240 meters per second, as compared to Earth’s 343 meters per second, (per the Jet Propulsion Laboratory), owing to Mars’s thin, carbon-dioxide-rich atmosphere.

This meteor was an interstellar house crasher

In October of 2017, astronomers got their first glimpse of an interstellar object in our solar system when ‘Oumuamua came racing through past the Sun, (per NASA). While it’s likely that interstellar objects have visited our solar system before and probably do so pretty frequently, (per Cosmos), this was the first time we had seen it in action. At least, that’s what we thought.

Now, it turns out there may have been an interstellar meteor that impacted Earth three years earlier, in 2014. The Center for Near-Earth Object Studies tracked the object to its impact point off the coast of Papua New Guinea. At the time, it was thought to have been your ordinary everyday meteor impact, no big deal, but later analysis suggests it came from elsewhere in the galaxy.

Perseverance reaches Jezero Delta

Perseverance's path

Since landing at Jezero Crater, Perseverance has taken a winding path toward Jezero Delta, the remains of an ancient river delta that is believed to have housed water in the past. At long last, it’s finally made it. According to NASA, there is evidence that water flowed into the area, created the delta, and water flowed out.

Anywhere on Mars where there once was water could make a good candidate for finding evidence of past life, but the delta is especially good because water stuck around there for a long time. If life ever existed on Mars, this is as good a place as any to find it.

The solar eclipse on Mars

Perseverance used its Mastcam-Z camera system which is intended to take panoramic and 3D images of the Martian environment while the rover makes its way along the surface. While NASA has captured several eclipses from the Martian surface in the past, going back to Spirit and Opportunity, the Mastcam-Z provided full color, the highest zoom, and the best frame rate to date.

As explained by NASA, Phobos is only about 17 miles across at its widest point and it moves pretty fast, orbiting Mars three times per day. As a result, the eclipse was relatively brief, lasting only about 40 seconds

Two black holes merged

The Laser Interferometer Gravitational-Wave Observatory (LIGO) was built in hopes of confirming the existence of gravitational waves. Those waves are essentially ripples in space-time resulting from huge mass shifts like those occurring when two black holes meet. Mind-Blowing Scientific Discoveries In 2022
