SpaceX, Boeing Commercial Crew flights delayed by NASA (again)

The agency's Commercial Crew Program has been working with SpaceX "throughout the month of January" to make sure it is "ready to learn critical information that will further help us to fly our crews safely", officials said. Recovery crews will haul the craft to shore for detailed post-flight examination. The rocket performed a static fire test on the pad January 24 that the company said was successful.

NOAA/NASA: 2018 Was Fourth Hottest Year On Record

Continuing a trend of rising temperatures, 2018 was the fourth hottest year on record , according to a climate change report out Wednesday from NASA and the National Oceanic and Atmospheric Administration (NOAA). That would be warmer than the last four years. Schmidt also said that increasing temperatures can also contribute to longer fire seasons and some extreme weather events. Consulte Mais Informação

2018 was the fourth-hottest year on record

Using much of the same data, NOAA estimates that global temperatures were 1.42 degrees Fahrenheit (0.79 degrees Celsius) higher than the 20th-century average. "That is not saying the Paris Agreement is done for. but it's a worrying sign", he said. January 1 to December 31, 2018, according to NASA. The Paris pact responded to a 1992 United Nations treaty under which all governments agreed to avert "dangerous" man-made climate change . Consulte Mais Informação

Unexpected magnetic north pole changes mean new world magnetic model map

Unexpected magnetic north pole changes mean new world magnetic model map

Scientists were in the middle of arranging an emergency location update for its location when the USA government shutdown put the announcement on hold. WMM provides a five year forecast of changes to the Earth's magnetic field. The U.S.' National Oceanic and Atmospheric Administration (NOAA) said in a statement Monday that scientists had updated the World Magnetic Model, used by smartphone and consumer electronics for maps and Global Positioning System services, ahead of time to account for ...

Check your compass: The magnetic north pole is fast on the move

The constant shift is a problem for compasses in smartphones and some consumer electronics. However, the magnetic north pole is moving faster than normal resulting in a new out of cycle release for the WMM. 'We might just call it magnetic weather'. 'It has changes akin to weather, Mr Lathrop said. It could be thousands of years before the magnetic field reverses again, the researchers believe. Consulte Mais Informação

Climate Change Will Soon Change The Colour of Our Oceans. Here's How

Climate Change Will Soon Change The Colour of Our Oceans. Here's How

The research effort for the new finding was two-fold: Scientists built a detailed model of phytoplankton communities across the globe to accurately simulate the impacts of climate change on the ratios of different algae species. "Other things will absorb or scatter it, like something with a hard shell". It all comes down to a tiny organism called phytoplankton, or algae, which contains chlorophyll and lives in the ocean.

The Milky Way in a twist

The Milky Way in a twist

A group of astronomers from Australia and China have built their " intuitive and accurate three-dimensional picture " by mapping the so-called " classical Cepheids ". "It is notoriously hard to determine distances from the Sun to parts of the Milky Way's outer gas disc without having a clear idea of what that disc actually looks like", says Xiaodian Chen, lead author, from the Chinese Academy of Sciences in Beijing.

Study Suggests Neanderthals And Denisovans Lived Together In A Cave

The findings are published this week in the journal " Nature ". Stone tools indicated one or both species may have occupied the cave starting 300,000 years ago. 2019. Age estimates for hominin fossils and the onset of the Upper Palaeolithic at Denisova Cave. "The improved age estimates for the hominin fossils obtained using the novel Bayesian age model, incorporate all of the dating evidence available for these small and isolated fossils, which can sometimes be displaced after deposition ...

NASA's Parker Solar Probe completes its first trip around the sun

NASA's Parker Solar Probe completes its first trip around the sun

On Jan. 19, it reached its aphelion point, or the farthest orbital distance from the sun, and has now started its orbital trip. It is expected to reach the next perihelion, or the closest point to the sun, on April 4. It will have its final flyby in 2025 when it will dive within just 3.83 million miles of the sun. This brings it closer to the blinding light, unbelievable temperatures and huge gravity of the prior record holder-Helios 2. Consulte Mais Informação
