Discovered a visitor named 2015 BZ509 from another solar system orbiting Jupiter upside down

A mysterious asteroid orbiting Jupiter dodging asteroids in its path, in addition to doing so in the opposite direction to the rest of space bodies of the solar system.(2015 BZ509)

2015 BZ509

The so-called asteroid, is known as 2015 BZ509 and has an orbit contrary to the rest of bodies that orbit our sun. The most surprising thing is that, in turn, it shares the orbital space of Jupiter. It is the only asteroid in the solar system that does not travel in programmed motion. And this opens the debate of whether it really is an asteroid.

In our solar system almost 900 thousand asteroids are known and all share the same system of orbital movement. However, 2015 BZ509 has its own system (natural or not) of movement. This supposed asteroid travels clockwise, and not vice versa, which is how the rest of bodies move.

This proves that the mysterious celestial body travels against the flow of energy that the gravitating force of the sun and the rest of bodies of great volume exert against it. Surprisingly, the 2015 BZ509 is propelled inexplicably, avoiding all kinds of objects like a camicace.

The autonomous asteroid, which has a size of 300 kilometers, manages to dodge all kinds of objects that travel in counter-direction without suffering any collision that slows or deviates its regular travel route. And each time it crosses Jupiter (which is a thousand times larger than Earth), it does so by sharing orbital space and, in turn, bypassing the thousands of asteroids that travel alongside the gas giant.

2015 BZ509

A challenge for the enigmatic asteroid and also for science, which does not know what it faces or can not explain the behavior of that body. But the truth is that, 2015 BZ509 has been doing the same route regularly since at least one million years. This means thousands and thousands of returns to the solar system, without having undergone any change.

It is thought that this asteroid (if it is), would have been from the beginning of the solar system, that means about 4,500 million years. It was detected at the beginning of the year and gave a lot to talk about due to its characteristics. It is a carbon-rich asteroid and formed outside the solar system. It is not known where it comes from.

Sara Rosell, from the Natural History Museum of the United States, points out that the work of science is to discover the origin of the universe and in this case, discover what this object is. It does not want to label it as an asteroid, because its behavior is not that of a regular asteroid, or at least, not one that is known with that characteristic.

As astronomy explains, everything that was formed from the gas disk and the primordial debris of its star, follow the direction of the rotation of its parent star. However, 2015 BZ509 does not behave in the same way. And maybe we are still too immature intellectually to understand the mystery that is presented to us.

Milky Way galaxy is warped and twisted, not flat

Our galaxy, the Milky Way, is “warped and twisted” and not flat as previously thought, new research shows.

Analysis of the brightest stars in the galaxy shows that they do not lie on a flat plane as shown in academic texts and popular science books.

Astronomers from Warsaw University speculate that it might have been bent out of shape by past interactions with nearby galaxies.

The new three dimensional map has been published in the journal Science.

The popular picture of the Milky Way as a flat disc is based on the observation of 2.5 million stars out of a possible 2.5 billion. The artists’ impressions are therefore rough approximations of the truer shape of our galaxy, according to Dr Dorota Skowron of Warsaw University.

“The internal structure and history of the Milky Way is still far from being understood, in part because it is extremely difficult to measure distances to stars at the outer regions of our galaxy,” she said.

To gain a more accurate picture, Dr Skowron and her colleagues measured the distances of some of the brightest stars in the Milky Way, called Cepheid variable stars. These are massive young stars that burn hundreds, if not thousands, of times brighter than our own Sun. They can be so bright that they can be observed at the very edge of the galaxy.

Not only that, they also pulsate at regular intervals at a rate that is directly related to their brightness.

Artists’ impressions which depict the Milky Way as a flat disk will have to be revised

This enables astronomers to calculate their distance with great precision.

Most of the stars were identified by the Optical Gravitational Lensing Experiment (OGLE) at Las Campanas Observatory (LCO) in Chile’s southern Atacama Desert. Przemek Mroz, a member of the OGLE team, said that the results were surprising.

“Our results show that the Milky Way Galaxy is not flat. It is warped and twisted far away from the galactic centre. Warping may have happened through past interactions with satellite galaxies, intergalactic gas or dark matter (invisible material present in galaxies about which little in known).”

The Polish results support an analysis of Cepheid variable stars published in February in Nature Astronomy journal by astronomers from Macquarie University in Australia and the Chinese Academy of Sciences.

SpaceX Starship update coming later this month

Starship could carry the first astronauts back to the Moon.

Elon Musk’s private space firm has been developing a spacecraft capable of landing humans on other worlds.

Designed to serve as the reusable second stage of the Big Falcon Rocket (BFR), Starship will also be able to carry astronauts and cargo all the way to the surface of Mars.

The spacecraft has undergone several name changes since it was first announced, having previously transitioned from Mars Colonial Transporter (MCT) to Interplanetary Transport System (ITS).

Now Elon Musk has revealed that a full update on the project will be coming on August 24th at either Cape Canaveral in Florida or Boca Chica in Texas, which is where a prototype was recently tested.

Writing on Twitter, he stated that the update would include a “detailed review of the first orbital Starship, explaining the pros and cons of each design decision.”

“We should have Starship Mk1 with 3 Raptors almost ready to fly by then,” he said.

It will certainly be interesting to see how things are progressing.

Exoplanet With 3 Suns a Great Site to Search for Alien Life

A newly discovered planet with three suns is exciting scientists for its close proximity to Earth and its potential for future observation, including possible signs of extraterrestrial life.

LTT 1445Ab is just 22.5 light-years away and was found using data gathered by NASA’s Transiting Exoplanet Survey Satellite (TESS), which searches for exoplanets.

The planet orbits just one of its three red dwarf stars, circling it every five days. It’s thought to be a third bigger than Earth, but has about eight times the mass of our planet and a temperature of about 320 degrees Fahrenheit.

“If you’re standing on the surface of that planet, there are three suns in the sky, but two of them are pretty far away and small-looking,” research co-author Jennifer Winters told New Scientist. “They’re like two red, ominous eyes in the sky.”

Because of its relative proximity to Earth, LTT 1445Ab could be used to look for potential signs of alien life.

Scientists think the planet could potentially have an atmosphere, and that they can examine the area for gases like carbon dioxide using new detection tools ready in the near future. LTT 1445AB will present plenty of opportunities for observations because of its speedy orbits around its sun.
