Space is so vast, it’s bound to contain a ghoul or two. This particular ghostly visage, captured by the Hubble Space Telescope in 2019, is actually two galaxies in the process of colliding with one another. What looks like eyes are the bright cores of each galaxy, and the outline of the face is a ring of young blue stars that formed as a result of the ongoing collision. The two galaxies will merge completely in about 1 to 2 billion years. Image credit: NASA/ESA/J. Dalcanton/B.F. Williams/M. Durbin.

Apollo 17 lunar samples are yielding new discoveries. New analysis of lunar material brought back by the Apollo 17 mission in 1972 suggests that the Moon may be 40 million years older than we thought. Researchers studied a sample of zircon in the Moon rocks, a mineral that would have been the first solid to form when the Moon’s surface solidified. The team established the age of the zircon as 4.46 billion years, older than the previous estimate of the Moon’s age, which was 4.42 billion years.

The University of California and NASA Ames are planning to build a new space center. The Berkeley Space Center campus will be built at the University of California, Berkeley, in Mountain View, California. Its purpose will be to house research and development facilities for the university and private partners, focusing on space robotics, remote sensing, planetary sciences, climate change, electric aviation, mixed autonomy traffic operations, and firefighting.
