New research is helping to explain one of the big questions that has perplexed astrophysicists for the past 30 years — what causes the changing brightness of distant stars called magnetars.
Magnetars were formed from stellar explosions or supernovae and they have extremely strong magnetic fields, estimated to be around 100 million, million times greater than the magnetic field found on earth.
The magnetic field generates intense heat and x-rays. It is so strong it also affects the physical properties of matter, most notably the way that heat is conducted through the crust of the star and across its surface, creating the variations in brightness across the star which has puzzled astrophysicists and astronomers.
A team of scientists — led by Dr Andrei Igoshev at the University of Leeds — has developed a mathematical model that simulates the way the magnetic field disrupts the conventional understanding of heat being distributed
CHEOPS has released the results of its observation on alien planet WASP-189b
WASP-189b’s orbit is tilted dramatically and orbits its star every 2.7 Earth days
WASP-189b has temperatures reaching 5,800 Fahrenheit
The European Space Agency’s Characterizing Exoplanet Satellite (CHEOPS) has recently discovered an alien planet about 1.6 times the size of Jupiter. Aside from having a strange orbit, it is also scorching hot.
WASP-189b, the newly discovered alien planet, was first detected in 2018 and has been recorded to have temperatures reaching 5,800 Fahrenheit — almost as hot as Earth’s outer core and is even hot enough to turn iron into gas, ESA’s study revealed.
Aside from having a size comparable to Jupiter, the exoplanet is also considered a “Hot Jupiter” due to its extremely short orbital period (2.7 Earth days). A Hot Jupiter is a gas planet with a “Jupiter-like” size that orbits very close to its
On Tuesday, the Pew Research Center released survey results that represent a picture of how the publics of 20 different countries view science and the technologies it enables—or at least how those countries viewed science and tech immediately before the pandemic struck. The good news is that there’s widespread trust in scientists and a strong desire to act on their findings on issues like climate change.
But the results also contain plenty of reasons for concern. Some of the outcomes of scientific development, such as genetically modified foods, are widely mistrusted by the public in most countries. And, in many countries, there’s a large partisan divide in views of scientists—and the divide is the most extreme in the United States.
Normally, we’d spend some time discussing the details of how survey data was gathered. But with 20 countries, each with its own independent
In 2012, an extreme solar storm nearly hit the Earth
Researchers studying the event said it could have been more extreme if paired with another event
Researchers demonstrated how two solar storms could interact with each other
Solar storms could become more powerful if they happen quite close to each other, researchers studying the 2012 solar storm have found.
On July 23, 2012, a solar storm, which NASA describes as the most powerful one in about 150 years, nearly hit the Earth. Had it hit the Earth, it would have caused an economic impact of over $2 trillion and the damages could take years to repair.
The 2012 near-miss has been likened to the 1859 Carrington Event, one of the biggest solar storms on record, that caused auroras as far south as Cuba and Honolulu.
Coronal Mass Ejections (CME) are outbursts of plasma from the sun that
Hot Jupiters are Jupiter-like exoplanets located in close proximity to their host stars, hence their name. Ultra-hot Jupiters are basically the same thing, but, as you’ve probably guessed, they’re even hotter. Back in 2018, astronomers using the ground-based WASP-South telescope in South Africa detected an ultra-hot Jupiter dubbed WASP-189b, unlike anything seen before.
Two years later, using the brand-spanking-new Characterising Exoplanet Satellite (CHEOPS) space telescope, astronomers have gazed upon this celestial wonder with new eyes, refining what we know of this unusual exoplanet, while at the same time affirming the tremendous potential of this European space telescope, which only began making scientific observations this past April.
Eight months after the space telescope CHEOPS started its journey into space, the first scientific publication using data from CHEOPS has been issued. CHEOPS is the first ESA mission dedicated to characterising known exoplanets. Exoplanets, i.e. planets outside the Solar system, were first found in 1995 by two Swiss astronomers, Michel Mayor and Didier Queloz, who were last year awarded the Nobel Prize for this discovery. CHEOPS was developed as part of a partnership between ESA and Switzerland. Under the leadership of the University of Bern and ESA, a consortium of more than a hundred scientists and engineers from eleven European states was involved in constructing the satellite over five years. The Science Operations Center of CHEOPS is located at the observatory of the University of Geneva.
Using data from CHEOPS, scientists have recently carried out a detailed study of the exoplanet WASP-189b. The results have just been accepted for
Google has continued its fight against Australia’s news media bargaining code, this time attacking the final offer arbitration process, known as baseball arbitration, that will be used.
In such a process, rather than parties agreeing to a deal, an arbitrator is presented with a final offer from each side and must select one of the offers presented. Google is arguing that Australia’s old media are asking for sums far in excess of what Google generates from searches related to news, which it says is around AU$10 million in revenue.
“Clearly, both sides have very different ideas of what the prices should be — and asking the arbitrator to pick a ‘final offer’ is an extreme way of resolving that,” Google ANZ chief Mel Silva said in a blog post.
“The reality is that baseball arbitration often fails and doesn’t produce quick outcomes. Independent economists have raised questions about its effectiveness.”
