Astronomers Discover Supersonic Winds on Distant Exoplanet

DEGermany|

Astronomers have made a groundbreaking discovery regarding the exoplanet WASP-127b, located over 500 light-years from Earth. Research indicates that this gas giant experiences extremely high winds, reaching supersonic speeds of nearly 33,000 kilometers per hour (20,000 mph). This finding, published in the journal Astronomy & Astrophysics, highlights two distinct air currents on the planet: one moving towards Earth and the other retreating at the same remarkable speed.

Lead author Lisa Nortmann from the University of Göttingen explains that this phenomenon reveals a complex weather system comparable to those found on Earth. The planet, slightly larger than Jupiter but significantly less massive, is tidally locked, resulting in one side perpetually exposed to intense heat exceeding 1,000 degrees Celsius, while the opposite side remains in perpetual darkness.

WASP-127b was monitored using a high-resolution infrared spectrograph at the European Space Agency's Very Large Telescope in Chile, allowing researchers to gather detailed atmospheric data. The detection of these rapid winds and variations in temperature suggests the existence of complex atmospheric dynamics. This research not only advances understanding of WASP-127b but also contributes insights into the possible formation and evolution of planets beyond our Solar System.

Thermomix Customer Data Breach Affects Millions Worldwide

A significant data breach has compromised the personal information of around 3.1 million Thermomix customers, as reported by DER SPIEGEL. The breach occurred in the online recipe forum managed by Vorwerk, the manufacturer of the popular kitchen appliance, highlighting vulnerabilities in their data security protocols. According to Vorwerk, sensitive user information, including email addresses, residential addresses, and birthdates, was accessed and circulated on a dark web forum. The breach reportedly stemmed from a security flaw at an external service provider, allowing unauthorized access for several days. Customers in countries such as the Czech Republic, Spain, France, Italy, Poland, Portugal, and Australia were impacted. However, Vorwerk confirmed that financial information, including bank details and passwords, was not compromised. The company has pledged to notify affected users and is collaborating with authorities to investigate the incident. Vorwerk has also advised customers to be cautious of suspicious messages and not to engage with unknown contacts. They expressed sincere apologies for the inconvenience caused by this incident.

Holocaust Survivor Returns Honor Amid Rising Far-Right Concerns

Albrecht Weinberg, a 99-year-old Holocaust survivor, has announced his decision to return the Order of Merit he received from Germany in 2017 due to the recent political alliances between the Christian Democratic Union (CDU) and far-right parties. Weinberg, who was deported to Auschwitz at 18 and survived three concentration camps, expressed his alarm at the CDU's acceptance of support from the far-right Alternative für Deutschland (AfD) in pursuing anti-immigration measures. In a phone interview, he remarked, "It’s incredible that we’re back to this," emphasizing the potential for history to repeat itself under the influence of extremist politics. Following a failed anti-immigration bill supported by AfD, he noted that while there is hope, the political climate feels precarious. Weinberg, who has dedicated his post-war life to educating young Germans about the Holocaust, is scheduled to meet with President Frank-Walter Steinmeier, although he maintains his decision to return the honor. "The politicians have joined forces with right-wing extremists," he stated, reflecting his concerns about a democracy on the verge of collapse.

Husband on Trial for Murdering Wife with 82 Stab Wounds in Hamburg

A husband stands trial in Hamburg for allegedly murdering his wife, Helga K., by inflicting 82 stab wounds with a kitchen knife. The grisly incident, described as a "massacre" by emergency responders, occurred in their home in the Rönneburg district. According to reports, the couple, married for over 35 years, had a troubled relationship, characterized by increasing isolation and incidents of aggression from the husband, Georg K. The court heard that Georg K., a former Mercedes employee, may have suffered from depression and was in a diminished state of culpability at the time of the attack. On the night of the incident, a disagreement over an upcoming therapy appointment reportedly escalated into violence. Following the attack, Georg K. injured himself and called emergency services. Furthermore, investigators found that he conducted online searches in the days leading up to the murder regarding the implications of committing homicide under diminished capacity. The trial is set to continue on February 11.
