An exoplanet some 70% the mass of Jupiter and about 1.4 times its size has been discovered by astronomers at India’s Physical Research Laboratory (PRL). The behemoth is 752 light years away from Earth, and has an incredible orbit.
The new discovery was revealed by the Indian Space Research Organization on Tuesday in a statement saying the country’s PRL Advanced Radial-velocity Abu-sky Search (PARAS) had measured the movements of the newly-discovered exoplanet between December 2020 and March 2021.
The planet, named either HD 82139 or TOI 1789 depending on which cataloguing method is used, is ultra-hot – with a surface temperature up to 2,000 degrees Kelvin.
India’s PRL Advanced Radial-velocity Abu-sky Search (PARAS), an optical fiber-fed spectrograph, observed t he exoplanet and its movements from the Mt. Abu Observatory, according to the space agency. Not only is the planet ultra-hot, but it is also one of the closest to an orbiting star yet discovered.
The measurements obtained via PARAS were confirmed by Germany’s TCES spectrograph in April, and further verified by independent photometric observations from the PRL’s 43cm telescope, also located at Mt. Abu.
The exoplanet has an unusually quick orbit – a mere 3.2 days. The pace indicates that its distance from its host star is one-tenth the distance between Mercury and the Sun. This makes the exoplanet one of fewer than 10 such solar systems discovered thus far. Given the closeness to its host star – an aging orb 1.5 times the mass of the Sun – the new planet is also one of the lowest density planets yet discovered.
Planets so close to their host stars, with a distance less than 0.1 AU and masses between 0.25 to several times the mass of Jupiter, are known as “hot-Jupiters.”
The Indian space agency hailed the detection of the new planet as an opportunity to “enhance our understanding of various mechanisms responsible for inflation in hot-Jupiters and the formation and evolution of planetary systems around evolving and aging stars.” It is the second planet to be discovered by PARAS, with a previous discovery taking place in 2018.
Covid-battered global supply chains are being threatened by organized criminals, including drug cartels and con artists posing as legit suppliers, a new study has found, warning that the situation is set to get worse.
The international supply chain woes amid the Covid-19 pandemic are highlighted in a new annual report, released this week by the British Standards Institution (BSI).
The document, titled the ‘Supply Chain Risk Insights Report’, highlights Covid’s impact on supply chains, with the experts also warning that organized crime has increasingly preyed on this crucial area during the pandemic. On multiple instances, criminals were posing as legitimate logistics providers, stealing goods during shipment.
“I’m seeing a significant number of false suppliers acting as genuine potential suppliers in supply chain logistics provision – warehousing distribution, distribution centres, transportation companies – and actually, they are criminal groups trying to infiltrate the logistics supply chain,” said David Fairnie, BSI’s principal consultant in supply chain security. He urged producers to “continuously monitor” the supply chain and to not immediately trust new logistics providers – especially those contacted only remotely.
So, arguably today more than ever, you do need to know your suppliers. So far in 2021, BSI has noted this issue of fake carriers in an increasing number of countries in both the Americas and Europe.
Criminals have apparently been trying to steal goods in various ways, with phony truck drivers loading up items and taking off with them, while conmen “posing as legitimate employees” have reportedly been observed lurking around delivery destinations to steal cargo.
At the same time, the report found that trade in illicit goods has also been on the rise lately, with the illegal drug industry in particular appearing to flourish. While the supply chain for drug cartels, which require large amounts of assorted chemicals to produce narcotics, was disrupted due to the pandemic lockdowns and border closures impacted trafficking routes, organized crime quickly overcame these problems, the BSI noted.
“Drug cartels around the world did not miss a beat,” Chris Tomas, BSI lead intelligence analyst, said.
While many cartels shifted their production towards synthetic drugs, namely amphetamine, amid the pandemic, the apparent “lack of eradication of coca crops in Latin American countries” also remains an issue, the BSI said. The flow of cocaine has grown over the past year and is expected to increase even further, the organization warned.
“The numbers and quantities of cocaine seizures in Europe increased steadily in 2020 and 2021 and are expected to continue to rise in 2022,” the report reads.
