It is set to fly into the Sun's corona within 3.8 million miles or 6.1 million km from the solar surface, seven times closer than any other spacecraft. Being the first-ever mission of NASA to "touch" the Sun, the Parker Solar mission is about the size of a small vehicle that will travel directly into the Sun's atmosphere. (more...)
New storm forms over Atlantic; no threat to Jamaica New storm forms over Atlantic; no threat to Jamaica
- August 16, 2018

A turn toward the north-northeast is forecast tonight, and a faster northeastward motion is expected by late Thursday and should continue through early Saturday. Tropical-storm-force winds extend outward up to 35 miles from the center. Ernesto will spend the next day over marginally warm sea surface temperatures and in a low-shear environment - which will lead to some strengthening. (more...)

The launch of the United Launch Alliance Delta IV Heavy rocket carrying the spacecraft was scrubbed on Saturday due to a violation of a launch limit, resulting in a hold. It will fly directly through the Sun's atmosphere, as close as 3,8-million miles from its surface, closer to the surface than any spacecraft before it. (more...)

France to set penalities on non-recycled plastic France to set penalities on non-recycled plastic
- August 15, 2018

Asked whether it was sufficient to count on the goodwill of industry to reach Macron's target of 100 percent plastic recycling by 2025, Poirson said that imposing new regulation too quickly would lead to defensive reactions. She noted that glass, unlike plastic, is "infinitely recyclable". Chatel added that while focusing on recycling is absolutely needed and is a welcome move, it is not enough. (more...)

NASA second attempt at solar probe launch NASA second attempt at solar probe launch
- August 14, 2018

Over the next two months, Parker Solar Probe will fly towards Venus, performing its first Venus gravity assist in early October - a maneuver a bit like a handbrake turn - that whips the spacecraft around the planet, using Venus's gravity to trim the spacecraft's orbit tighter around the Sun. (more...)

- August 13, 2018

NASA researchers trust they have discovered new proof of a odd "divider" encompassing our close planetary system. Of course, the team acknowledges that similar findings from the Voyager spacecraft and the New Horizon probe are not enough evidence to definitively confirm the presence of a hydrogen wall. (more...)

No doubt some of you witnessed the stunning natural display caused by the Perseid meteor shower last night . This time the shower will be especially visible thanks to the August 11 new moon, leaving a dark and hopefully clear sky. The Perseids take their name from the constellation Perseus, the constellation from which they are thought to have originated. The phase of the moon (new moon) will make viewing even better, because the light from the moon will not ruined any visibility of the ... (more...)

The $1.5 billion (£1.2 billion) probe, which is the size of the auto, will play a vital role in our understanding of the solar system. The probe will dip inside this tenuous atmosphere, sampling conditions, and getting to just 6.16 million km (3.83 million miles) from the Sun's broiling "surface". (more...)
Man finds 25-million-year-old shark teeth Man finds 25-million-year-old shark teeth
- August 11, 2018

The pair of fossilized teeth are from a prehistoric great jagged narrow-toothed shark nearly twice the length of today's great white. Most of the teeth belonged to Carcharocles angustidens , but in addition, they found something even more surprising - several teeth of a smaller shark, the sixgill shark (genus Hexanchus ). (more...)
How to See the Amazing Perseid Meteor Shower in August 2018
- August 11, 2018

Unlike most meteor showers, the Perseids have a very broad peak, lasting until 4 a.m. ET on August 12. Usually, on these peak nights it will produce 60-70 meteors an hour, but in bursts the rate can go up to 200 an hour. The best time to view is in the pre-dawn hours. The Perseids actually got their name from the constellation Perseus. The Perseid meteor shower is an August treat every year because the Earth passes through a trail left by the 16-miles-wide comet of dust, ice, rock and ... (more...)

Air quality advisory issued in Clark County Air quality advisory issued in Clark County
- August 11, 2018

The Minnesota Pollution Control Agency Wednesday put much of northwestern and north-central Minnesota under an air quality alert through Thursday morning as a smoke plume makes its way southeast out of western Canada. These potential negative health impacts may be exacerbated by prolonged smoke or ozone exposure. Due to active wildfires and changing wind patterns, air quality throughout the Bay Area is likely to be impacted through most of the week. (more...)

If it launches successfully at the same time on Sunday, the probe will reach speeds of up to 430,000 miles per hour (700,000 km/h). The reason for the delay was not immediately clear, but was called for after a gaseous helium alarm was sounded in the last moments before liftoff, officials said. (more...)

Tahlequah is part of the Southern Resident population which the NOAA Fisheries says is critically endangered. If that goes well, they say they will try feeding her Chinook salmon filled with other medication. "If they're travelling, it's challenging", said Hanson. "That's what this is really all about". It was hearing initial recommendations focused on three main threats to the orcas: lack of food, toxic contamination and boat noise and disturbance. (more...)
Stargazing conditions prime for meteor shower Stargazing conditions prime for meteor shower
- August 11, 2018

That's more than a meteor per minute. The moon light won't fade them out either, because there will only be a sliver left in as it approaches the new moon stage. Meteor showers are named after the constellation of stars the meteors radiate from. If you're out looking for meteors in the city, it's worth finding the darkest spot you can, far from streetlights, and getting your eyes used to the dark for a half hour or so. (more...)
