A planet of their own

Filed under
Sci/Tech

A HUGE new planet has been discovered by a team of Tasmanian scientists.

The huge, gaseous planet, called OB-05-071, is in the Milky Way between Earth and the centre of the galaxy, about 20,000 to 25,000 light years away.

The odds of the find were one in 10 million, according to Stefan Dieters of the the Canopus Observatory team at Cambridge, which found the new planet.

On three nights in April, Dr Dieters and Kym Hill were in the right place at the right time to identify the new planet, 1000 times the size of Earth.

The news will be posted on Harvard University's Centre for Astrophysics' NASA-sponsored website at 10am today.

The University of Tasmania team is part of an international project code-named PLANET, co-ordinated by the Paris Institute for Astrophysics, which is pioneering the use of gravitational microlensing to look for new planets.

PLANET has telescopes ringing the southern hemisphere, in Hobart, Perth, Chile and South Africa, enabling members to keep watch at night continuously for 24 hours after an alert.

Dr Dieters and Dr Hill were at Canopus when alerted to the possibility of the new planet by MOA, an independent group in New Zealand.

Ryzen 3 Linux Gaming Benchmarks: NVIDIA vs. AMD Radeon

This week I posted some fresh OpenGL vs. Vulkan benchmarks on the AMD Ryzen 3 while for this weekend article are some more Linux gaming benchmarks from the budget-friendly Ryzen 3 1200 and Ryzen 3 1300X processors. On the Ryzen 3 1200 and Ryzen 3 1300X, NVIDIA's GeForce GTX 1050 and GTX 1060 graphics cards were tested while on the Radeon side was the RX 560 and RX 480 graphics cards.

Some Fresh I/O Scheduler Benchmarks: Linux 4.13 With BFQ, CFQ, Kyber, Deadline

For those curious about the state of I/O schedulers with the in-development Linux 4.13 kernel, here are some fresh disk benchmarks using the 4.13 Git kernel on an Intel laptop/ultrabook and testing the various in-kernel options. Tests were done from a Broadwell era Lenovo ThinkPad X1 Carbon with SSD. In the days ahead I'll have some tests as well from a slower, rotational media system. Read more
