New observations and simulations by a research team led by MPE show that a massive binary star near the center of our Galaxy is creating a series of enigmatic gas clouds, compact clumps that help feed the supermassive black hole Sagittarius A*.

NASA’s Psyche Spacecraft Is About To Fly Shockingly Close to Mars
NASA’s Psyche spacecraft is using a daring close flyby of Mars to slingshot toward one of the solar system’s strangest asteroids.
New critical Exim mailer flaw allows remote code execution
A critical vulnerability affecting certain configurations of the Exim open-source mail transfer agent could be exploited by an unauthenticated remote attacker to execute arbitrary code.
Identified as CVE-2026–45185, the security issue impacts some Exim versions before 4.99.3 that use the default GNU Transport Layer Security (GnuTLS) library for secure communication. It is a user-after-free (UAF) flaw triggered during the TLS shutdown while handling BDAT chunked SMTP traffic.
Exim frees a TLS transfer buffer but later continues using stale callback references that can write data into the freed memory region, which can lead to unauthenticated remote code execution (RCE).
Windows BitLocker zero-day gives access to protected drives, PoC released
A cybersecurity researcher has published proof-of-concept (PoC) exploits for two unpatched Microsoft Windows vulnerabilities named YellowKey and GreenPlasma, which are a BitLocker bypass and a privilege-escalation flaw.
Known as Chaotic Eclipse or Nightmare Eclipse, the researcher describes the BitLocker bypass issue as functioning like a backdoor because the vulnerable component is present only in the Windows Recovery Environment (WinRE), which is used to repair boot-related issues in Windows.
The latest exploits follow the researcher’s previous disclosure of the BlueHammer (CVE-2026–33825) and RedSun (no identifier) local privilege escalation (LPE) as zero-day flaws, both of which began to be exploited in the wild shortly after being publicly disclosed.
