This week in space saw a mix of controversy, new discoveries, and anniversaries. NASA faced criticism for its all-male Artemis 3 crew, while a new study shed light on the Fermi Paradox, and astronomers discovered how supermassive black holes feed themselves.
Controversy Over NASA's All-Male Artemis 3 Crew
NASA's recent announcement of its Artemis 3 crew sparked controversy due to the absence of female astronauts. The four-person crew, comprising NASA's Randy Bresnik, the European Space Agency's Luca Parmitano, and NASA mission specialists Andre Douglas and Frank Rubio, was selected based on qualifications, according to NASA officials. However, the lack of female representation has raised eyebrows, given that women make up around 40% of NASA's active astronauts.
A New Take on the Fermi Paradox
Professor David Kipping of Columbia University has proposed a new model, known as the Cosmological Hart-Tipler Conjecture (CH-TC), which offers a fresh perspective on the Fermi Paradox. The paradox, which questions the apparent lack of extraterrestrial civilizations, has been debated for decades. Kipping's model suggests that the probability of advanced life existing in the universe is lower than previously thought.
Supermassive Black Holes' Feeding Habits
Astronomers have made a groundbreaking discovery about the feeding habits of supermassive black holes. Using the James Webb Space Telescope (JWST), researchers observed a swirl of ionized gas within the sphere of influence of a black hole in the Centaurus cluster. This finding provides new insights into how these massive objects accrete material and regulate the evolution of their galaxies.

What Experts Say
"I don't think anyone should be reading into this." — NASA Chief, on the all-male Artemis 3 crew
Background
The Fermi Paradox has been a topic of debate among scientists and theorists for decades. The paradox is named after physicist Enrico Fermi, who famously asked, "Where is everybody?" during a lunchtime conversation at Los Alamos National Laboratory.
What Comes Next
As NASA prepares for the Artemis 3 mission, the agency will face increased scrutiny over its crew selection process. Meanwhile, researchers will continue to study the Fermi Paradox and the behavior of supermassive black holes, shedding new light on the mysteries of the universe.
