Hubble captures image of 'hidden galaxy'

Hubble captures image of 'hidden galaxy'

Science
July 7 (UPI) -- The Hubble Space Telescope captured the IC 342, a challenging space target due to its thick glowing gas, dark, bright stars and obscuring dust.The IC 342, also known as the Hidden Galaxy, sits near the equator in the Milky Way's galactic disk, where the haze of glowing cosmic gas, dark, obscuring dust and bright stars was captured in an image released by NASA on Friday.Scientists had to look through a large amount of material contained within our own galaxy to view the intricate spiral structure of IC 342.IC 342 gets its name of the Hidden Galaxy because of difficulty viewing it, and it would be among the brightest galaxies in the sky if it wasn't obscured by cosmic dust.The very active galaxy is a mixture of hot, blue star-forming regions, redder, cooler regions of gas, an...

Media playback is unsupported on your deviceThe two satellites that make up the BepiColombo mission to Mercury were presented to the media on Thursday. This joint European-Japanese venture has been in development for nearly two decades, but should finally get to the launch pad in 15 months' time.The two spacecraft will travel together to the baking world but separate on arrival to conduct their own studies.Thursday's event in the Netherlands was the last chance for journalists to view the so-called "flight stack".This is the edifice that goes on top of the rocket and comprises Europe's Mercury Planetary Orbiter (MPO) and Japan's Mercury Magnetospheric Orbiter (MMO), as well as the propulsion module to control their path towards the world that circles closest to the Sun.As a single item, th...

G20 Hamburg: Leaders fail to bridge Trump climate chasm

Science
Leaders of 19 nations at the G20 summit in Germany have renewed their pledge to implement the Paris deal on climate change, despite the US pulling out.Deadlock over the issue had held up the last day of talks in Hamburg but a final agreement was eventually reached.It acknowledges President Donald Trump's withdrawal from the Paris climate agreement without undermining the commitment of other countries.The compromise comes after violent protests in the host city.The joint summit statement released on Saturday said: "We take note of the decision of the United States of America to withdraw from the Paris Agreement."However, the leaders of the other G20 members agreed the accord committing nations to restrict global temperature increases was "irreversible".In her closing news conference, German...
Research finds why rappelling spiders spin in control

Research finds why rappelling spiders spin in control

Science
July 7 (UPI) -- Researchers found in a recent study that spider silk partially yields when twisted, which prevents rappelling spiders from spinning out of control.The study, published in the July edition of Applied Physics Letters, showed that, unlike human hair, metal wires or synthetic fibers, spider silk partially yields when twisted to resist spinning."Spider silk is very different from other, more conventional materials," Dabiao Liu of Huazhong University of Science and Technology, said in a press release. "We find that the dragline from the web hardly twists, so we want to know why."Spiders use dragline silk for the outer rim and spokes of their webs as well as a lifeline for dropping to the ground.Researchers used a torsion pendulum to investigate dragline silk from two species of g...
