El Ojo ‘The Eye’ Island Location: Buenos Aires, Argentina

El Ojo ‘The Eye’ Island Location: Buenos Aires, Argentina

First discovered by Argentinian filmmaker Sergio Neuspiller in 2003, El Ojo is an uninhabited circular rotating floating island located within a slightly larger circular lake in the Paraná Delta in the Buenos Aires Province, Argentina. This island is constantly rotating on its own axis due to the flow of the river beneath it. The island was named because of its resemblance to an eye when viewed from above: as the island rotates within its surrounding circular lake, the eye appears to move.

Scientists find slowest spinning 'radio neutron star' — it breaks all the dead-star rules
Space.com
ASKAP J1935+2148 will have other dead stars turning in their graves.

Astronomers have discovered the slowest spinning radio wave-blasting neutron star ever seen; it takes almost an hour to complete a full rotation.  That may sound rather fast, but these dead stars are known to spin so rapidly that some experience 700 full turns every second. Even the most leisurely of the about 3,000 radio-emitting neutron stars, or "pulsars," discovered so far complete a full rotation in a second or so. This ultra-leisurely neutron star, however, designated ASKAP J1935+2148 and located 16,000 light-years from Earth, is emitting radio light at a rate too slow to even fit with current theories describing the behavior of these dense stellar remnants.

So Venus is my favorite planet in the solar system - everything about it is just so weird.

A photo of the planet Venus, showing its opaque white atmosphere.

It has this extraordinarily dense atmosphere that by all accounts shouldn't exist - Venus is close enough to the sun (and therefore hot enough) that the atmosphere should have literally evaporated away, just like Mercury's. We think Earth manages to keep its atmosphere by virtue of our magnetic field, but Venus doesn't even have that going for it. While Venus is probably volcanically active, it definitely doesn't have an internal magnetic dynamo, so whatever form of volcanism it has going on is very different from ours. And, it spins backwards! For some reason!!

But, for as many mysteries as Venus has, the United States really hasn't spent much time investigating it. The Soviet Union, on the other hand, sent no less than 16 probes to Venus between 1961 and 1984 as part of the Venera program - most of them looked like this!

A picture of one of the Soviet Union Venera probes. The probe is a squat hourglass shape, with a wide, circular base for stability, and a large circular radio antenna on top.

The Soviet Union had a very different approach to space than the United States. NASA missions are typically extremely risk averse, and the spacecraft we launch are generally very expensive one-offs that have only one chance to succeed or fail.

It's lead to some really amazing science, but to put it into perspective, the Mars Opportunity rover only had to survive on Mars for 90 days for the mission to be declared a complete success. That thing lasted 15 years. I love the Opportunity rover as much as any self-respecting NASA engineer, but how much extra time and money did we spend that we didn't technically "need" to for it to last 60x longer than required?

Anyway, all to say, the Soviet Union took a more incremental approach, where failures were far less devastating. The Venera 9 through 14 probes were designed to land on the surface of Venus, and survive long enough to take a picture with two cameras - not an easy task, but a fairly straightforward goal compared to NASA standards. They had…mixed results.

Venera 9 managed to take a picture with one camera, but the other one's lens cap didn't deploy.

Venera 10 also managed to take a picture with one camera, but again the other lens cap didn't deploy.

Venera 11 took no pictures - neither lens cap deployed this time.

Venera 12 also took no pictures - because again, neither lens cap deployed.

Lotta problems with lens caps.

For Venera 13 and 14, in addition to the cameras they sent a device to sample the Venusian "soil". Upon landing, the arm was supposed to swing down and analyze the surface it touched - it was a simple mechanism that couldn't be re-deployed or adjusted after the first go.

This time, both lens caps FINALLY ejected perfectly, and we were treated to these marvelous, eerie pictures of the Venus landscape:

Two photos side-by-side of the Venus surface - one from the front facing camera of the Venera probe, and one from the backwards facing camera. The sky is a strange yellow-green, and the ground is rocky and cracked. The atmosphere is so thick that you can't see further than a few hundred feet into the distance.

However, when the Venera 14 soil sampler arm deployed, instead of sampling the Venus surface, it managed to swing down and land perfectly on….an ejected lens cap.

i find it so unfair that i cant do all the science. like what do you MEAN I can't study bio and chem and biochem and atrophysics and physics and geology and climate science. what do you MEAN i have a limited lifespan and need to get out of school at some point to get a job. i want to collect the science fields like pokemon, this isn't fair

These 'failed stars' orbit so closely it took 29 years to tell they were a pair
Space.com
"Gliese 229B was considered the poster-child brown dwarf, and now we know we were wrong all along about the nature of the object. It's not o

A well-studied cosmic object has stunned astronomers. The "failed star" Gliese 229B has been revealed to be two so-called "brown dwarfs" that are closely orbiting each other rather than just one. The revelation means that Gliese 229B is a "first-of-its-kind" tight brown dwarf binary, increasing the hope other such exotic systems dwell in the Milky Way just waiting to be discovered. The finding also solves a long-standing mystery about Gliese 229B, explaining why this brown dwarf appears too dim for its mass.  "Gliese 229B was considered the poster-child brown dwarf," team member and California Institute of Technology (Caltech) researcher Jerry W. Xuan said in a statement. "And now we know we were wrong all along about the nature of the object. It's not one but two. We just weren't able to probe separations this close until now."
