The pursuit of extraterrestrial life has taken a significant leap forward as the world-renowned National Science Foundation’s Karl G. Jansky Very Large Array (VLA) joins the quest.

The VLA’s focus is on detecting technosignatures, emissions unique to artificial transmitters, with the potential to reveal advanced civilizations beyond our own.

Situated about 50 miles west of Socorro, New Mexico, the VLA is a remarkable radio astronomy observatory, boasting 27 antennas spread across 23 miles of desert terrain. Since 2017, the VLA has participated in the Very Large Array Sky Survey (VLASS) project. Its new mission involves collecting and analyzing data during VLASS observations, using a specialized receiver to identify narrow-band components in signals from intentionally engineered transmitters and differentiate them from natural occurrences.

The SETI Institute leads this groundbreaking effort in collaboration with the National Radio Astronomy Observatory and the Breakthrough Listen Initiative. The new processing system for SETI is named COSMIC (Commensal Open-Source Multimode Interferometer Cluster).

VLA expert Paul Demorest explains, “COSMIC operates commensally, meaning it functions in the background, using a copy of the data astronomers are obtaining for other scientific purposes.”

COSMIC can identify various transmissions, such as pulsed and transient signals, while monitoring an impressive range of frequencies and examining around ten million star systems. Since 2023, COSMIC has detected signals from Voyager 1, the most distant human-made object, currently located about 15 billion miles away.

Combining the VLA’s unparalleled sensitivity with the COSMIC system makes this SETI search about a thousand times more comprehensive than previous efforts. This collaboration could potentially uncover a radio whisper, suggesting that we are not the only intelligent inhabitants of the Milky Way Galaxy.

Tony Beasley, Director of the NRAO, expressed enthusiasm for the partnership, stating, “The National Radio Astronomy Observatory is proud to partner with the SETI Institute in this exciting initiative. Partnerships that bring together world-class research instruments, private research institutes, and members of the public personally committed to forefront science can enable new important discoveries.”

As the VLA and COSMIC continue searching for extraterrestrial life, researchers and scientists worldwide eagerly await the results. Detecting technosignatures would mark a turning point in human history, transforming our understanding of our place in the cosmos and unlocking new avenues for scientific exploration and collaboration.

Even if the search does not yield immediate results, the collected data will still provide invaluable information for other areas of astronomical research. This could potentially offer new insights into galaxy formation, dark matter distribution, and enigmatic cosmic phenomena like fast radio bursts.

This partnership combines resources and expertise to enhance the likelihood of detecting technosignatures and expand our understanding of the universe. Ultimately, it aims to answer the age-old question of whether we are alone in the universe.

The Super Pressure Balloon Imaging Telescope (SuperBIT) has taken its first images of the cosmos from the edge of space.

Astronomers are hoping to gain valuable data that could help unravel the mysteries surrounding dark matter.

On April 16, the stratospheric observer was carried to a high altitude above Earth’s atmosphere by a football field-sized NASA helium balloon in its first operational flight.

During the flight, SuperBIT captured images of the Tarantula Nebula, a region within the Large Magellanic Cloud, which is a satellite galaxy of the Milky Way located approximately 160,000 light-years from Earth. This immense cloud of gas and dust, spanning 931 light-years, is a hotbed of star formation. The telescope also obtained images of the Antennae galaxies, NGC 4038 and NGC 4039, which are located around 60 million light-years away in the southern constellation of Corvus. These galaxies are currently experiencing a collision and merger that likely began a few hundred million years ago, making them the closest and youngest examples of colliding galaxies.

SuperBIT’s primary goal is to capture images of galaxies in the visible-to-near ultraviolet light spectrum. Although the Hubble Space Telescope covers this range, SuperBIT offers a wider field of view. To study dark matter, the telescope will utilize gravitational lensing, a natural phenomenon predicted by Einstein’s theory of general relativity. Gravitational lensing occurs when massive objects like galaxies warp spacetime, causing light to bend as it travels along the curvature.

Dark matter, which does not interact with electromagnetic radiation or light, is virtually invisible. However, it does interact with gravity, allowing astronomers to infer its presence. Gravitational lensing is an ideal method for mapping dark matter’s distribution, and SuperBIT may help scientists determine whether dark matter particles can bounce off one another when galactic clusters collide. Such research could finally reveal the composition of dark matter particles.

Professor Richard Massey from Durham University explained that SuperBIT would observe clusters of galaxies colliding with each other. He stated, “Essentially, we’re using the largest particle accelerators in the universe to smash lumps of dark matter and see where the bits fly.” He added, “If dark matter goes ‘crunch’, or if bits are chipped off, we could finally start to learn what it’s made of.”

SuperBIT, a collaboration between NASA, Durham University, the University of Toronto, and Princeton University, launched from Wānaka, New Zealand. The telescope and its super-pressure balloon can travel around the globe at an altitude of approximately 21 miles (34 kilometers) for 100 days, above 99.5% of Earth’s atmosphere. This vantage point enables SuperBIT to gather scientific data and take high-resolution images without the blurring effect of the atmosphere.

The telescope can be safely returned to Earth via parachute, allowing the team to update its design. Funding has already been secured to upgrade SuperBIT’s 1.6 feet (0.5-meter) aperture telescope to 5.2 feet (1.6 meters), equipping it with a wider-angle lens and increased megapixels for the camera. This enhancement will increase its light-gathering power tenfold.

With a price tag of approximately $5 million, the balloon-carried telescope represents a significantly more economical option compared to rocket-launched instruments. In fact, SuperBIT costs almost 1,000 times less than equivalent satellite missions. NASA officials envision that the relatively low cost of SuperBIT could pave the way for a fleet of these telescopes to be deployed above Earth, collectively exploring the enigmas of the universe with greater affordability and accessibility.

On April 14th,  the esteemed Ariane 5 rocket carried out its second-to-last mission, launching a European spacecraft on an eight-year voyage to Jupiter.

The Ariane 5 lifted off from Kourou, French Guiana’s European spaceport, after unfavorable weather postponed the launch the day before. The Jupiter Icy Moons Explorer (JUICE) spacecraft successfully detached from the Ariane upper stage 26 minutes after liftoff.

Ground controllers established communication with JUICE approximately 40 minutes after liftoff. Shortly after, they deployed the spacecraft’s two large solar arrays, which cover a total area of 85 square meters and will provide power for the six-ton probe.

The signal acquisition from JUICE took slightly longer than anticipated but remained within the normal range. Solar array deployment occurred sooner than expected, which Jean-Marc Nasr, head of space systems at Airbus Defence and Space, explained was due to precise sun acquisition by spacecraft systems. He deemed it “a sign of a perfect mission.”

The launch marks the beginning of JUICE’s lengthy journey to Jupiter and its three largest moons. The Airbus-built spacecraft will utilize several gravity-assist flybys to reach its destination, starting with a joint Earth-moon flyby in August 2024, followed by additional Earth flybys in September 2026 and January 2029, and a Venus flyby in August 2025.

Upon reaching Jupiter in July 2031, JUICE will conduct 35 flybys of Europa, Ganymede, and Callisto, investigating their surfaces and underground oceans to determine habitability. The spacecraft will orbit Ganymede from December 2034 until the mission’s conclusion in September 2035.

Josef Aschbacher, ESA’s director general, expressed pride in the mission, stating it addresses “questions of science that are burning to all of us.”

The mission, which has an estimated cost of 1.5 billion euros ($1.65 billion), will utilize ten instruments, including one contributed by NASA. The Japanese space agency JAXA and Israel Space Agency are also partners, providing components for other instruments.

This launch marks the sixth time an Ariane 5 rocket has carried ESA missions, including the December 2021 launch of NASA’s James Webb Space Telescope with significant ESA contributions. Since 1996, there have been a total of 116 Ariane 5 launches.

Only one Ariane 5 flight remains, tentatively scheduled for late June, carrying two European government communications satellites, France’s Syracuse 4B and Germany’s Heinrich Hertz.

Stéphane Israël, Arianespace’s CEO, described the final launches as a “wonderful symbol” for France and Germany. The Ariane 5 will be replaced by the Ariane 6, whose maiden flight has been delayed multiple times. The latest target for the Ariane 6 debut is late 2023, though there is speculation it may be pushed back further.

While Aschbacher did not provide a new estimate for the Ariane 6 launch, he expressed confidence in its progress, saying, “We have to go through some decisive milestones in the next couple of weeks, but certainly we are on a good track.” He acknowledged feeling a tinge of sadness about Ariane 5’s retirement but expressed optimism that Ariane 6 will be “an equally good launcher.”
