NASA Parker Solar Probe launches on mission to high-five the sun

perth_map

Now, with the help of cutting-edge thermal technology that can protect the mission on its unsafe journey, the spacecraft's four instrument suites will study magnetic fields, plasma and energetic particles, and image the solar wind . Among its many purposes the Parker Solar Probe will try to answer two key questions surrounding the Sun. Roughly the size of a small auto, PSP will get almost seven times closer to the sun than any previous spacecraft. Read More »

Will clouds obscure your view of the Perseid meteor shower?

perth_map

Moonless nights will make the spectacle of the annual Perseid meteor shower even more scintillating this weekend for much of the world, and sky watchers are expecting a "great show". "If it's clear, we should be able to see quite a few". Others are brighter and can appear to sail across our sky for several seconds, leaving a glowing smoke trail. Read More »

It later updated that the launch was "scrubbed" and a second attempt will be made on Sunday morning. The probe is named for Eugene Parker, 91, a University of Chicago physicist who in 1958 predicted the existence of the solar wind, a constant flow of magnetized solar particles that streams out into the farthest reaches of the solar system.

How PIO physicist laid foundation for NASA's mission to 'touch' the Sun

perth_map

As soon as this fall, the Parker Solar Probe will fly straight through the wispy edges of the sun's corona , or outer atmosphere, that was visible during last August's total solar eclipse . A worst-case scenario could cost up to two trillion dollars in the first year alone and take a decade to fully recover from, experts have warned. The Parker Solar Probe will have to travel about 430,000 miles per hour and use a high-tech heat shield to survive the trip . Read More »

Where to see the last partial solar eclipse of 2018

perth_map

Sometimes, the moon only partially covers the sun, creating a partial solar eclipse , or doesn't completely obscure the sun (an annular, or "ring of fire", eclipse ). During the lunar eclipse, the moon crossed the ecliptic - the apparent path of the sun in our sky - while at full phase on July 27, resulting in our natural satellite passing through the shadow of the Earth (hence the total lunar eclipse).

Perseid meteor shower to lit up Qatar sky Saturday

perth_map

The annual Perseid Meteor Shower is peaking this weekend over Mid-Michigan! According to Space.com, this year's peak will be visible both the nights of August 11-12 and August 12-13. The Perseids are caused by the Earth passing through a comet's debris field, according to the American Meteor Society. Arriving by that time should give your eyes ample time to adjust to the darkness. Read More »

Perseid Meteor Shower To Put On Brilliant Show This Weekend

Since the Perseids radiate from the northeast, you will generally see more meteors with shorter tails when watching the northern sky. She recommends anywhere it's dark, outside the city, for the best views. And don't forget to grab your camera before you head out. Better still, viewing conditions this time around are particularly ideal - due to a new moon. Read More »

perth_map

EDT, the Parker Solar Probe will launch from Space Launch Complex 37 on Florida's Cape Canaveral Air Force Station. In seven years, the probe will be within four million miles of the sun's surface. The Parker Solar Probe will endure tremendous heat while zooming through the solar corona to study this outermost part of the stellar atmosphere that gives rise to the solar wind. Read More »

Meteor shower of the year coming up

People can view the meteors streaming across the sky anywhere away from downtown Lawrence. As long as you're in the Northern Hemisphere, the Perseid meteor shower will be right overhead. To make the best of the meteors, observers should avoid built-up areas and try to find an unobstructed view to the east. As always, it's best to get away from light pollution and head far away from city centers. Read More »

Perseids 2018: Where and how to watch the dazzling meteor shower

But there is no need to search for the constellation because the shooting star will zoom across the sky in ever direction conceivable. The peak will be from 9.00 pm on Sunday 12th August to 4.30 am on Monday 13th August. Timeanddate.com provides tables indicating when the showers are active and even gives some nice tips on how to best watch the performance. They should start whizzing across the sky before midnight, but the best displays will be in the hours before dawn. Read More »

Single farmers without families are also eligible to received up to $3,600. "We would also like farmers to be aware that the Rural Financial Councillors services come at no cost to them", Mr Jackson said. The Australian Bureau of Meteorology has forecast still drier conditions and says there is no end in sight to the drought.

The volcano is in the middle of a three-month eruption of lava which has been spewing since May and has covered 13.4 square miles of the island's surface. "Hector is our first hurricane this year", said Tom Travis, administrator of Hawaii Emergency Management Agency, in a press release on Friday. Some fluctuations in intensity are expected overnight into Monday, followed by gradual weakening Monday night through Wednesday. Read More »

Subtropical Storm Debby forms in north Atlantic

perth_map

A growing hurricane absorbed a tropical storm off Mexico's Pacific Coast today and a new subtropical storm formed in the northern Atlantic, though none were projected to make landfall. The tropical Atlantic remains cooler than normal and there is a relatively high potential that a weak El Niño develops in the next several months. Depending on its ultimate track, the storm could bring thunderstorms, gusty winds and increased surf to parts of the island and could also cause unsafe rip ... Read More »

Hallinan said . Brown dwarfs have long baffled experts because they're too big to be considered planets but are not big enough to be stars. The scientists found that the object's magnetic field is more than 200 times stronger than Jupiter's , which, in turn, is between 16 and 54times stronger than Earth's, according to NASA. Read More »

Boeing CST-100 Starliner and SpaceX Dragoncapsules will carry eight active NASA astronauts and one former astronaut-turned-corporate crew member to the International Space Station starting next year. While it will be Glover's first time in space, Hopkins has previously logged 166 days aboard the space station in 2014. Once the Starliner and Dragon capsules are operational, NASA will no longer need to rely on Russia's Soyuz rocket and spacecraft to launch astronauts into low-Earth orbit. Read More »

Scientists Just Received a Massively Powerful Signal Coming from Deep Space

perth_map

Fast radio bursts are extremely unusual, with the first discovered in 2007 and only two dozen recorded since then. According to the sources, this is the lowest frequency FRB in history - picked up by CHIME at a frequency below 700 MHz. Most of the time such kind of radio telescopes don't hear anything that's abnormal, but now an unexplained signal made its way through the noise. CHIME was created to detect ancient radio waves sent out when the universe was just a toddler, some 6 billion to ... Read More »
