NASA Restores Communications with Voyager 1 The venerable Voyager 1 spacecraft is finally phoning home again. This is much to the relief of mission engineers, scientists, and Voyager fans around the world. On November 14, 2023, the aging spacecraft began sending what amounted to a string of gibberish back to Earth. It appeared to be getting commands from Earth and seemed to be operating okay. It just wasn’t returning any useful science and engineering data. The team engineers began diagnostic testing to figure out if the spacecraft’s onboard computer was giving up the ghost. They also wanted to know if there was some other issueRead More →

Will We Know if TRAPPIST-1e has Life? The search for extrasolar planets is currently undergoing a seismic shift. With the deployment of the Kepler Space Telescope and the Transiting Exoplanet Survey Satellite (TESS), scientists discovered thousands of exoplanets, most of which were detected and confirmed using indirect methods. But in more recent years, and with the launch of the James Webb Space Telescope (JWST), the field has been transitioning toward one of characterization. In this process, scientists rely on emission spectra from exoplanet atmospheres to search for the chemical signatures we associate with life (biosignatures). However, there’s some controversy regarding the kinds of signatures scientistsRead More →

Astronaut Food Will Lose Nutrients on Long-Duration Missions. NASA is Working on a Fix Astronauts on board the International Space Station are often visited by supply ships from Earth with food among other things. Take a trip to Mars or other and the distances are much greater making it impractical to send fresh supplies. The prepackaged food used by NASA loses nutritional value over time so NASA is looking at ways astronauts can produce nutrients. They are exploring genetic engineering techniques that can create microbes with minimal ingredients.  Many of us take food and eating for granted. The food we can enjoy is usually flavoursomeRead More →

There Was a Doomed Comet Near the Sun During the Eclipse A surprise appearance of a new comet made the April 8th total solar eclipse all the more memorable. Any dedicated ‘umbraphile’ will tell you: no two eclipses are exactly the same. Weather, solar activity, and the just plain expeditionary nature of reaching and standing in the shadow of the Moon for those brief moments during totality assures a unique experience, every time out. The same can be said for catching a brief glimpse of what’s going on near the Sun, from prominences and the pearly white corona to the configuration of bright planets… andRead More →

The Ingenuity Team Downloads the Final Data from the Mars Helicopter. The Mission is Over I really can’t believe that the Ingenuity helicopter on Mars took its maiden voyage in April 2021. On the 16th April 2024, engineers at NASA have received the final batch of data from the craft which marks the final task of the team. Ingenuity’s work is not over though as it will remain on the surface collecting data. For the engineers at NASA, they have their sights set on Dragonfly, a new helicopter destined for Titan. When Ingenuity took off on its maiden voyage it became the first powered craftRead More →

Juno Reveals a Giant Lava Lake on Io NASA’s Juno spacecraft came within 1,500 km (930 miles) of the surface of Jupiter’s moon Io in two recent flybys. That’s close enough to reveal new details on the surface of this moon, the most volcanic object in the Solar System. Not only did Juno capture volcanic activity, but scientists were also able to create a visual animation from the data that shows what Io’s 200-km-long lava lake Loki Patera would look like if you could get even closer. There are islands at the center of a magma lake rimmed with hot lava. The lake’s surface isRead More →

What’s the Most Effective Way to Explore our Nearest Stars? It was 1903 that the Wright brothers made the first successful self-propelled flight. Launching themselves to history, they set the foundations for transatlantic flights, supersonic flight and perhaps even the exploration of the Solar System. Now we are on the precipice of travel among the stars but among the many ideas and theories, what is the ultimate and most effective way to explore our nearest stellar neighbours? After all, there are 10,000 stars within a region of 110 light years from Earth so there are plenty to choose from.  It’s not just the stars thatRead More →

Radiating Exoplanet Discovered in “Perfect Tidal Storm” Can tidal forces cause an exoplanet’s surface to radiate heat? This is what a recent study accepted to The Astronomical Journal hopes to address as a team of international researchers used data collected from ground-based instruments to confirm the existence of a second exoplanet residing within the exoplanetary system, HD 104067, along with using NASA’s Transiting Exoplanet Survey Satellite (TESS) mission to identify an additional exoplanet candidate, as well. What’s unique about this exoplanet candidate, which orbits innermost compared to the other two, is that the tidal forces exhibited from the outer two exoplanets are potentially causing theRead More →
