The Robert Koch Institute, Germany’s disease control agency, has warned that the country will face a “really terrible Christmas” unless steps are taken to mitigate a huge rise in Covid-19 cases.
Speaking on Thursday, the director of the Robert Koch Institute, Lothar Wieler, reiterated the case for new, strict countermeasures to prevent the spread of Covid-19.
“We are currently heading toward a serious emergency,” Wieler stated, adding “we are going to have a really terrible Christmas if we don’t take countermeasures now.” He added that hospitals were already struggling to find enough beds.
Wieler has called for a campaign for a further increase in vaccine uptake, from the current 67% to well over 75%.
The diseases institute director also believes bars, nightclubs, and other large-scale venues should be temporarily forced to close, and that other areas of public life should be off-limits to the unvaccinated.
His comments come as German leaders ponder new restrictions to replace the nationwide epidemic rules, which could include a lockdown of the unvaccinated, following measures already taken in neighboring Austria.
On Thursday, in an attempt to counter waning immunity levels, the country’s vaccine advisory board recommended that booster shots be made available to everyone aged 18 or above.
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.
