When stars like our Sun, between 40% and ~800% of our mass, run out of hydrogen in their core, they start to die.

The core contracts and heats up, causing the outer layers to expand as the star becomes a helium-burning red giant.

From Nature: “1,500 scientists lift the lid on reproducibility”

More than 70% of researchers have tried and failed to reproduce another scientist’s experiments, and more than half have failed to reproduce their own experiments. Those are some of the telling figures that emerged from Nature’s survey of 1,576 researchers who took a brief online questionnaire on reproducibility in research.

The data reveal sometimes-contradictory attitudes towards reproducibility. Although 52% of those surveyed agree that there is a significant ‘crisis’ of reproducibility, less than 31% think that failure to reproduce published results means that the result is probably wrong, and most say that they still trust the published literature.

Data on how much of the scientific literature is reproducible are rare and generally bleak. The best-known analyses, from psychology1 and cancer biology2, found rates of around 40% and 10%, respectively. Our survey respondents were more optimistic: 73% said that they think that…

From CosmosUp: “May 30: Mars to Make The Closest Approach to Earth In 11 Years”

Don’t miss!!! On Monday, May 30, Mars will be closer to Earth than it has been in 11 years and it will shine 10 times brighter than it did at the start of 2016.

2016 – Planet MARS

Last week on May 22, Mars reached opposition with the sun, meaning the Earth was between Mars and the Sun, but that phenomena did not mark Mars’ closest approach to Earth. On May 30, Mars Will be 47.2 million miles (75.3 million kilometers) from Earth, that’s more than 500,000 miles closer to our planet than at opposition.

So, it is a great opportunity to stargazer to catch a glimpse of Mars as will appear bigger and brighter than usual to us until June 3.

Mars is easy to view with the naked eye, you don’t need a telescope or binoculars to see it, probably you will be…

The Web They Want: How a twitter wordsearch justifies internet censorship

OffGuardian

by Kit

streetartnews_above_socialmedia-6

Earlier this year the Guardian launched their new campaign – “The Web We Want”. It’s an agenda driven campaign to suppress free speech and protect the ancien media regime from the alt-news revolution, in the name of protecting ethnic minorities, female writers and the LGBT community from the all the hate that pours out of the privileged fingertips of all the white men on the internet.

We have written extensively on what the Guardian really means by “the web they want”. We know their statistics are a farce and can see through their editorial double talk. Their place in a planned roll out of an idea is obvious, coinciding with political climbers from all parties making speeches attacking free speech in the name of freedom. Banning liberty because…won’t somebody please think of the children!

When the Guardian talks about “taking action” against internet abuse, we know…

24 SPRINGTIME IN THE STRATOSPHERE

reality

This chapter explores the characteristics of the atmosphere in spring.  It relates the distribution of ozone and NOx  to ozonesonde data  and the temperature and movement of the air. My data sources are  here for maps showing ozone and NOx profiles and here for ozonesonde data and here for maps showing temperature, pressure and wind.

The objective is to investigate the factors responsible for the composition, temperature, density and movement of the air. The discussion pertains to the origin of  the planetary winds, cloud cover and surface temperature, in short climate change.

Ozone 50hPa 6 hr

Above: Ozone at 50 hPa 11th to 13th September at six hourly intervals.

The diagrams above show ozone at the 50 hPa pressure level (20km) in the southern hemisphere at 6 hourly intervals. Observe that the rotation of the atmosphere  above the Antarctic continent over 54 hours amounts to about half a circle. A full rotation at…

Claim: Climate Causes More Young Girls to be Raped

Another sickening low.

Watts Up With That?

According to Reuters, in Guatemala, young girls don’t get raped because they are stalked by filthy perverts, who are shielded by what appears to be a rape enabling culture; Apparently Climate Change is to blame.

Women’s organisations – and funders – are increasingly seeing climate change as a root cause of women’s problems

COPENHAGEN, May 20 (Thomson Reuters Foundation) – Carla Lopez remembers the first time she heard a suggestion that climate change was a factor leading to the rape of young girls.

“I was in Santa Maria Xalapan of Guatemala when a group of women said young girls were being kidnapped and raped because there was a water crisis. It was a revelation,” said the…

From Hubble: “Hubble Catches Views of a Jet Rotating with Comet 252P/LINEAR”

For thousands of years, humans have recorded sightings of mysterious comets sweeping across the nighttime skies. These celestial wanderers, “snowballs” of dust and ice, are swift-moving visitors from the cold depths of space. Some of them periodically visit the inner solar system during their journeys around the sun.

Astronomers using NASA’s Hubble Space Telescope captured images of Comet 252P/LINEAR just after it swept by Earth on March 21.

Swarm tracks Earth’s turbulent magnetic field 

blink-and-you-miss-it indeed!

The BBC report by Jonathan Amos includes two ‘blink-and-you-miss-it’ videos that offer a global view of the magnetic patterns. The three-year east-west oscillation sounds interesting.

Europe’s Swarm mission is providing an unprecedented view of Earth’s turbulent magnetic field, scientists say. The three-satellite constellation is now routinely mapping its convulsions, allowing researchers to probe the mechanisms that drive the “invisible shield” in remarkable new detail.
