Introduction

Space exploration and astronomy are two fields that are constantly advancing and revealing new insights into the universe and its wonders. In this article, we will review some of the latest discoveries and innovations in space exploration and astronomy that happened in September 2023.

Water on Mars

One of the most exciting discoveries in space exploration was the confirmation of water on Mars by NASA’s Perseverance rover. The rover drilled a sample from a rock named “Rochette” in the Jezero Crater, which was once a lake billions of years ago. The sample contained traces of salt minerals that indicate the presence of liquid water in the past¹. This discovery has important implications for the search for life on Mars, as water is essential for life as we know it.

Proxima Centauri b

Another fascinating discovery in astronomy was the detection of a possible atmosphere around Proxima Centauri b, the closest exoplanet to Earth. Proxima Centauri b is a rocky planet that orbits within the habitable zone of its star, Proxima Centauri, which is about 4.2 light-years away from us. Using the ALMA telescope, astronomers observed a faint signal that could be caused by molecules in the planet’s atmosphere, such as water vapor or carbon dioxide². This discovery raises the possibility that Proxima Centauri b could support life, or at least have a climate similar to Earth’s.

Gravitational Waves

A third remarkable discovery in astrophysics was the observation of gravitational waves from a rare event: the merger of a black hole and a neutron star. Gravitational waves are ripples in space-time caused by massive objects accelerating or colliding. The event, dubbed GW200105, was detected by the LIGO and Virgo detectors on January 5th, 2020, but it took more than a year to confirm and analyze it³. This discovery provides new information about the properties and behavior of black holes and neutron stars, as well as the origin and evolution of heavy elements in the universe.

New Horizons

A fourth impressive innovation in space exploration was the achievement of New Horizons, NASA’s spacecraft that explored Pluto and its moons in 2015. New Horizons became the first spacecraft to reach 50 astronomical units (AU) from the sun, which is equivalent to 50 times the distance between Earth and the sun⁴. This milestone marks New Horizons as one of the most distant and longest-operating spacecraft ever launched. New Horizons is still active and exploring the outer solar system, with its next target being a Kuiper Belt object named 2014 MU69, or Ultima Thule.

Some other recent discoveries in space exploration and astronomy are:

• The discovery of a new type of supernova that is brighter and faster than any other known supernova. The supernova, named SN 2022jli, was detected by the Zwicky Transient Facility (ZTF) in May 2022 and studied by an international team of astronomers. The supernova is classified as a Type Ic supernova, which means that it is the result of the core collapse of a massive star that has lost its hydrogen and helium layers. However, SN 2022jli is different from other Type Ic supernovae in that it reached its peak brightness in just 2.2 days and faded by more than 50% in 4 days, making it the fastest and most luminous supernova ever observed¹.
• The detection of a possible biosignature on Venus, a planet that is often considered inhospitable for life. A team of astronomers using the James Clerk Maxwell Telescope (JCMT) and the Atacama Large Millimeter/submillimeter Array (ALMA) found traces of phosphine, a gas that is associated with life on Earth, in the clouds of Venus. The presence of phosphine on Venus could indicate the existence of microbial life in the planet’s atmosphere, or it could be explained by some unknown chemical or geological process².
• The launch of the James Webb Space Telescope (JWST), the most powerful and complex space telescope ever built. The JWST was launched on December 25, 2022, after years of delays and challenges. The JWST is designed to observe the infrared light from the earliest stars and galaxies in the universe, as well as the formation of planets and the potential for life beyond Earth. The JWST will also complement and extend the discoveries of the Hubble Space Telescope, which has been operating since 1990³.
• The discovery of a new moon around Jupiter, the largest and most diverse planetary system in our solar system. The moon, named Ersa, was discovered by an amateur astronomer named Kai Ly using images from NASA’s Juno spacecraft. Ersa is about 1 kilometer (0.6 miles) in diameter and orbits Jupiter at a distance of about 23 million kilometers (14 million miles). Ersa is the 80th known moon of Jupiter and belongs to a group of irregular moons that have eccentric and inclined orbits⁴.
