Using the European Southern Observatory (ESO)'s Very Large Telescope (VLT) in northern Chile's Atacama Desert, astronomers created this dramatic image of two giant planets in orbit around a star. About 300 light years from Earth, this is the first multiplanet system to be photographed that includes a star similar to our own Sun. The outer planet is six times more massive than Jupiter while the inner planet is 14 times heavier. The researchers published their work today in the Astrophysical Journal Letters

“Even though astronomers have indirectly detected thousands of planets in our galaxy, only a tiny fraction of these exoplanets have been directly imaged,” says co-author Matthew Kenworthy, Associate Professor at Leiden University, adding that “direct observations are important in the search for environments that can support life.” The direct imaging of two or more exoplanets around the same star is even more rare; only two such systems have been directly observed so far, both around stars markedly different from our Sun. The new ESO’s VLT image is the first direct image of more than one exoplanet around a Sun-like star. ESO’s VLT was also the first telescope to directly image an exoplanet, back in 2004, when it captured a speck of light around a brown dwarf, a type of ‘failed’ star.
“Our team has now been able to take the first image of two gas giant companions that are orbiting a young, solar analogue,” says Maddalena Reggiani, a postdoctoral researcher from KU Leuven, Belgium, who also participated in the study. The two planets can be seen in the new image as two bright points of light distant from their parent star, which is located in the upper left of the frame. By taking different images at different times, the team were able to distinguish these planets from the background stars.

Graham Clark, the 17-year-old Florida boy accused of pulling off the big Twitter hack, pled not guilty to charges on Tuesday. During the security breach, top accounts including Democratic presidential candidate Joe Biden and Tesla/SpaceX CEO Elon Musk were taken over to push a bitcoin scam.
In this footage, a supercomputer’s CPU cores — nearly 900 of them — are neatly lined up in the Task Manager. The Doom logo appears, generated by code that targets each core. Then Doom itself plays, each “pixel” generated by thrashing a core with just the right amount of busy work. Max Holt: Finally got […]
The UK government today ordered domestic companies to stop buying equipment from Chinese vendor Huawei and to stop using its kit entirely by 2027. Huawei is suspected to be an arm of the Chinese government, breaking into western markets (and maybe its networks) by selling impossibly cheap equipment. The UK only recently approved more Huawei […]
Now that the initial furor and shortages have subsided, it’s probably not a bad time to start considering your long-term cleaning and disinfecting plans. Sure, that might seem anywhere from overly cautious to outright ridiculous, but the threat of COVID-19 appears poised to be present for a while and the need for quick travel clean-up […]
With more and more companies moving all their operations into the cloud, the need has never been greater for those with the skills to map exactly how an organization reconstitutes itself in that new environment. Network architects responsible for determining all the communication, storage, and infrastructure needs of an expansive organization are among the most […]
Even after months of working from home, you’d be forgiven for thinking the whole experience still doesn’t quite feel…well, normal. In addition to all the obvious environmental changes of handling your 9 to 5 from your den or dining room table, the technological aids you didn’t realize you loved back at the office probably don’t […]
