Nothing excites space enthusiasts like a good alien mystery. The interstellar visitor ‘Oumuamua presented one as it moved through the inner solar system in 2017. At least one scientist has insisted that this pancake-shaped object is an alien spacecraft. That’s because of the way it accelerated away from the Sun as it passed through. However, a number of planetary scientists say its activity might be more comet-like—something fairly common in the solar system.

Number of Galaxies in the Known Universe
The observable universe is estimated to contain at least 100 billion galaxies, but this number could be much higher. This estimate is based on observations from the Hubble Space Telescope and other instruments that allow astronomers to observe a small portion of the universe and extrapolate the number of galaxies in the larger universe. However, there may be many more galaxies beyond what we are able to observe with current technology, which could increase the total number significantly.
Webb measures the temperature of a rocky exoplanet
An international team of researchers has used the NASA/ESA/CSA James Webb Space Telescope to measure the temperature of the rocky exoplanet TRAPPIST-1 b. The measurement is based on the planet’s thermal emission: heat energy given off in the form of infrared light detected by Webb’s Mid-Infrared Instrument (MIRI). The result indicates that the planet’s dayside has a temperature of about 500 kelvins (roughly 230°C), and suggests that it has no significant atmosphere.
Proba-3 complete: Formation-flying satellites fully integrated
The two spacecraft forming ESA’s Proba-3 mission for precise formation flying in orbit are now complete. All the instruments and sensors allowing them to manoeuvre to millimetre scale precision relative to one another have been integrated aboard, and the pair are fully wrapped in multi-layer insulation – ready to be tested in simulated space conditions.

Black holes may be swallowing invisible matter that slows the movement of stars
Scientists watched as two stars slowed in their orbits around black holes, concluding it was the result of "drag" generated by dark matter.
Why is Mercury so weird? Blame the giant outer planets.
Mercury is so strange that astronomers have not been able to explain its properties with simulations of the solar system's formation. But now, researchers have found an important clue.
Indian launch gives OneWeb enough satellites for global internet service

The successful launch of 36 more OneWeb satellites aboard India’s most powerful rocket Saturday brought the total number of OneWeb spacecraft in orbit to 618, enough for the London-based company to start global broadband service later this year.
