We've sent some pretty interesting payloads to space since the first satellite (Sputnik 1) launched on October 4th, 1957. As access to space has increased, thanks largely to the commercial space industry, so too have the types of payloads we are sending. Consider the Nyx capsule created by German aerospace startup The Exploration Company, which launched on June 23rd from the Vandenberg Space Force Base atop a Falcon-9 rocket as part of a rideshare mission (Transporter-14). The payload for this flight (dubbed "Mission Possible") included the ashes and DNA of more than 166 deceased people provided by Celestis, a Texas-based memorial spaceflight company.

If you could see the Universe through a radio-wave "eye", you'd detect mini-halos of relativistic particles creating radio emissions around some galaxy clusters. Astronomers long figured those halos are relative "recent" happenings in the nearby Universe and didn't occur in the early epochs of cosmic history. That's all changed now that the Low Frequency Array (LOFAR) radio observatory in Europe has revealed newborn galaxies in the early Universe already surrounded by a halo of particles. It's a rare look at what such clusters were like soon after they formed.

What can Earth-sized exoplanets teach scientists about the formation and evolution of exoplanets throughout the cosmos? This is what a recently submitted study hopes to address as an international team of researchers announced the discovery of an Earth-sized exoplanet that exhibits temperatures and a density comparable to Earth. This study has the potential to help scientists better understand the formation and evolution of Earth-sized exoplanets and what this could mean for finding life beyond Earth.

What can the pH level of the subsurface ocean on Enceladus tell us about finding life there? This is what a recent study accepted to Icarus hopes to address as a team of researchers investigated the potential pH level of Enceladus’ subsurface ocean based on current estimates. This study has the potential to help scientists better understand the composition of Enceladus’ subsurface ocean and what this can mean for finding life as we know it.

How accurate are the exoplanet radius measurements obtained by NASA’s Transiting Exoplanet Survey Satellite (TESS)? This is what a recent study accepted to The Astrophysical Journal hopes to address as a team of researchers investigated how hundreds of exoplanetary radii measured by TESS during its mission might be incorrect and the data could be underestimating the radii measurements. This study has the potential to help astronomers develop more efficient methods more estimating exoplanetary characteristics, which could influence whether or not they are Earth-sized.
