Look at the bigger one. | Ekoplanet Beta Pictoris b is moving around its parent star since December 2014, until it disappeared in a glittering star at the end of 2016. Then, two years later, astronomers saw how it reappears on the other side of its star. Pay attention to the position of the planet in the lower right corner, unlike others!

The European Southern Observatory (ESO) said on November 12, 2018 that its very large telescope took a series of unprecedented images showing the passage of the Beta Pictoris b team around its parent star. The pictures are above. They are incredible on the face, but especially when you notice the location of the ecoplanet in the lower right-hand view – that of September 2018 – unlike those that preceded it. In other words, this planet has gone in the splendor of its star for about two years. Then we could not even see it at all. But now she reappeared on the opposite side of her star, in order to make any respectable world moving in orbit.

We know that the worlds in the universe do it, but let's see! It's something new.

Only in the early 1990s, astronomers began to find planets around the giant sunlight. Now – despite the assumption that perhaps only billions of planets in our Galaxy Milky Vai – we were able to detect only a few thousand exoplanets. They found them in the splendor of their stars, which was a challenge. By their nature, the stars produce light; planets do not. Planets only shine a reflected light from their stars. So, seeing them in the glamor of their stars was a great challenge for astronomers for decades.

And this is still a challenge, although – as you see from this stunning image – technology has improved significantly.

Beta Pictoris b is a young massive ecoplanet, originally discovered through direct imaging in 2008, using the ESO's NACO instrument on a very large telescope. Most exoplanets are revealed when they pass or pass in front of their stars along our line of sight. But, from our earthly perspective, Beta Pictoris b does not exceed the transit, so had which can be found by direct imaging. The ESO said:

The same scientific team [that discovered it] having followed the exoplanet from the end of 2014 until the end of 2016, using the Spectro-Polarimetric High Contrast Instrument EKSOPLANET REsearch (SPHERE) – another instrument on a very large telescope.

Beta Pictoris b thus passed so much near the storm of a star that no instrument can solve them from each other. Nearly two years later, after it seems to merge into the picture of the star, Beta Pictoris b has now emerged from the halo. Recording again recorded SPHERE … [which] specializing in direct recording, hunting exoplanets taking their photos. This extremely difficult endeavor gives us clear images of distant worlds such as Beta Pictoris b, a distance of 63 light years.

Beta Pictoris b orbiting its star at a distance similar to that between the Sun and Saturn [approximately 800 million miles or 1.3 billion kilometers], which means it is the safest ecoplanet that has ever been directly recorded. The surface of this young planet is still hot, about 1,500 degrees Celsius [2,700 degrees Fahrenheit], and the light emitted enabled SPHERE to detect and track its orbit as it can be seen from its passage in front of the parent star.

The ESO also made a video clip of timelapse from these images, which you can see here. Enjoy!

Bottom line: Stunning a new set of images from the ESO's SPHERE instrument, which shows the passage of the Beta Pictoris b envoy to the glamor of its star, and then, two years later, reappears.
