14-inch spacecraft delivers new details about ‘hot Jupiters’
“The Colorado Ultraviolet Transit Experiment (CUTE) spacecraft is about the size of a cereal box. It has also recorded incredibly detailed measurements of the atmospheres of planets hundreds of light-years from Earth.”
It is the “size of a cereal box” and the purpose is to measure “hot Jupiter’s” atmosphere readings and Since its launch in September 2021, CUTE has trained its single ultraviolet telescope at a series of hot Jupiters, some hundreds of light-years from Earth.”
So, a Hot Jupiter?
“Hot Jupiters are among the hottest and angriest planets in the galaxy. As their name suggests, they are gas giants like our own Jupiter. These planets, however, hug much closer to their home stars, completing an orbit roughly once every several Earth days.”
And the good news?
“CUTE is still working and collecting data today.”

GALILEO: Scientists propose a new method to search for light dark matter
by Tejasri Gururaj , Phys.orgv.
A study, published today in The Astrophysical Journal, challenges the current model of the universe by showing that, in fact, it has no room for dark matter.Okay. I’ve been in the dark about that myself. However:
New research suggests that our universe has no dark matter
For Galileo: “Dark matter is one of the most pressing challenges in modern physics, with dark matter particles being elusive and hard to detect. This has prompted scientists to come up with new and innovative ways to look for these particles.
There are several candidates for dark matter particles, such as WIMPs, light dark matter particles (axions), and the hypothetical gravitino. Light dark matter, including bosonic particles like the QCD (quantum chromo dynamics) axion, has become a point of interest in recent years.”
“A study, published today in The Astrophysical Journal, challenges the current model of the universe by showing that, in fact, it has no room for dark matter.”
And also
“In standard cosmology, the accelerated expansion of the universe is said to be caused by dark energy but is in fact due to the weakening forces of nature as it expands, not due to dark energy.”
So, is it out there or not? We can argue among ourselves or forget it.
Last April, the first spaceship blew up 24 miles over the gulf of Mexico. In November The second almost made it to orbit, but both stages ended up exploding.
This time,
“Most of the flight proceeded smoothly, and a number of test objectives were achieved during the flight, like opening and closing the spacecraft’s payload doors, which will be needed to deliver cargo in the future.”
That is nicely done, but, [However], “the final landing burn for the booster, conducted over the Gulf of Mexico, did not fully succeed — an area that SpaceX will attempt to fix for future flights.”
SpaceX said the Super Heavy disintegrated at an altitude of about 1,500 feet.”
More details of all kinds of problems will arise. X wants to land astronauts on the moon. This means that the next one will have people in it. Remember the Challenger? Hopefully, enough lessons have been learned.
================================================
That is that that for this post. I will be posting poems during the week.
You don’t have to be big to be loud. Tiny fish can make noises louder than an elephant
“A small species of fish that measures no more than half an inch in length is capable of producing sounds louder than an elephant, according to a new study.
Danionella cerebrum,tiny translucent fish that live in shallow waters off Myanmar, can make noises of more than 140 decibels, an international team of scientists report in a press release published Tuesday.
‘This is comparable to the noise a human perceives of an airplane during take-off at a distance of 100 meter and quite unusual for an animal of such diminutive size,’ said study author Ralf Britz, an ichthyologist at the Senckenberg Natural History Museum in Dresden, Germany, in the press release.”
How does the half-inch fish do it?
“The fish make noise by hitting the cartilage against their swim bladder, a gas-filled organ that allows them to maintain depth in water, which produces a rapid pulse.
The use of both bilateral and unilateral contractions means that a greater variety of sounds can be produced, according to the study, and researchers say the fish use the pulses to communicate with each other in turbid waters.”
And maybe also competition between males.

We have littered the moon, put hardware on Mars, and now even asteroids aren’t safe from us.
NASA’s Crash Into an Asteroid May Have Altered Its Shape
The DART ( Double Asteroid Redirection Test) worked. The idea was to change the orbit of an asteroid to change its orbit away from earth, and it did.
“The world’s first-ever planetary defense experiment was deemed a triumph: The asteroid’s orbit shrank by 33 minutes, far above the minimum threshold of 73 seconds.”
Quite a triumph, but…
“But what the DART team didn’t realize then was just how bizarrely Dimorphos responded to that punch. A new study, published on Monday in Nature Astronomy, has concluded that DART hit Dimorphos so hard that the asteroid changed shape.”
They hadn’t expected it to pancake:
“Simulations of the impact suggest that the spacecraft’s death did not excavate a normal, bowl-shaped crater. Instead, it left behind something that resembles a dent. And although the artificial impact blasted millions of tons of rock into space, plenty splashed back onto its sides like tremendous tidal waves. It widened Dimorphos, transforming it from a squat orb into a flat-topped oval — like an M&M candy.”
But be careful with DART.
“DART showed that a tiny spacecraft can deflect an asteroid. But the study indicates that crashing a similarly disjointed space rock too forcefully risks fragmenting it, which, in a real asteroid emergency, could create multiple Earthbound asteroids.”
The asteroid consists of rocks held by gravity, so
“Like its previously explored asteroid siblings, Dimorphous responded in an unexpected way to being angrily prodded by a robot. That means that if the world requires saving from an inbound rubble pile, no assumptions can be made.”
Now, a semantic issue I’d more or less forgotten about until I needed this third item for this OION.
Hominin or Hominid?
What’s a Hominid? What’s a Hominin? Is there a difference?
“Yes, sort of.A Hominin, is AMH (Anatomically Modern Humans), all and all of our extinct ancestors. So bipedal walking apes. All members of the Homo Genus, Australopithecus Genus, and Paranthropus Genus, belong to the Hominin family.
“So then, what is a Hominid? Well that gets a little more confusing, most likely due to the fact that the usage of the word has changed in the last 100 years. Originally it was interchangeable with Hominin. There was no difference, they meant the same thing.
“But more recently taxonomists have been categorizing it as such:
A Hominid is any Human, Human Ancestor, Cousin, and all of the Great Apes, and their ancestors etc. So when using the terms, Hominid is much more broad and includes many more species, whereas Hominin is specifically for the Human Braided Stream.”
