New observational evidence from the James Webb Space Telescope (JWST), which has yet to launch, may change that. JWST astronomers have found tantalising hints of an orbiting gas giant around Alpha Centauri A, the closest Sun-like star to us. Located just four light-years away in the Alpha Centauri triple-star system, the potential planet sits within the star’s habitable zone — the region where liquid water could exist — but its gas giant nature makes it inhospitable to life. Even so, its location and distinctiveness make the detection among the most captivating detections in exoplanetary exploration prior.

JWST Unveils Possible Closest Sun-Like Star Exoplanet, Awaiting Confirmation

According to a NASA report, this was done with the JWST Mid-Infrared Instrument (MIRI) using a coronagraphic mask to block out stellar glare. This method caught sight of an object which is almost 10,000 times fainter than Alpha Centauri A and at a separation of around two astronomical units. If upheld, it would be the nearest exoplanet to a similar being ever pictured and, moreover, the first healthy globe discovered in direct significance.

Researchers noted that while Alpha Centauri already hosts two confirmed planets around the red dwarf Proxima Centauri, no planet has yet been confirmed around Alpha Centauri A. Follow-up JWST observations did not capture the planet again, possibly because it was too close to the star during the imaging. Computer simulations support this possibility.

The team wants to look for more evidence using both JWST and the yet-to-be-launched Nancy Grace Roman Space Telescope, due in May 2027. Confirmation would represent a watershed moment in planetary system science, where astronomers are looking into embryonic solar systems around other stars.

Researchers said the potential planet’s existence in such a dynamic binary star system could challenge current models of planetary formation and survival. Two papers detailing the findings have been accepted for publication in The Astrophysical Journal Letters.

Astronomers have discovered the most distant black hole yet, an ancient quasar more than 13 billion light years from our own Earth, incredibly close to the limit of where scientists even expect supermassive black holes to form. The cosmic behemoth of a galaxy, known as CAPERS-LRD-z9, provides a wide-window echo back in time to one of the furthest peeks into our early universe yet, only shortly after the Big Bang, when our cosmos was a fraction (3%) of its current age. Now, researchers led by those in The University of Texas at Austin’s Cosmic Frontier team have found what are likely very powerful gas outflows and also evidence that some of the very first black holes were born much, much heavier than previously believed.

Early Black Hole Found in ‘Little Red Dot’ Galaxy Challenges Growth Models

According to a study published in The Astrophysical Journal this week, researchers led by those at The University of Texas at Austin’s Cosmic Frontier team are announcing they have made the most sensitive measurements to date less than a billion years after the Big Bang, and these neonatal black holes were producing gas outflows fast enough — and over a long enough period — to halt stars forming in surrounding galaxies.

More recently discovered, the Little Red Dots galaxy appears to be just the sort of ominous-sounding crimson that would shoot a vibrant deep red due to intense radiation taking place among giant black holes and gas clouds.

A little galaxy of mass in all that more than enough of less, those hundreds of millions of suns among which all those stars are caught. This, in turn, birthed the supermassive galactic monsters — either quickly overcooked giants or premature sizes.

NASA’s interim leader Sean Duffy recently declared the U.S. space agency aims to place a 100-kilowatt nuclear reactor on the Moon by 2030 to provide energy for an eventual lunar outpost. Duffy describes this as a new moon race to establish the strategic foothold and keep a competitive advantage for the U.S. During a press conference titled “Unleashing American Drone Dominance” , he emphasised the importance of having dependable power on the lunar surface. NASA moved up its new crew-rushed lunar lander by a full year as the agency scrambles to seize key resources on the moon and lay the groundwork for deeper exploration at least four years away.

According to the press conference, for exploration and a long-term Moon base, reliable power is crucial. Solar panels fail during the Moon’s two-week-long nights, so a nuclear reactor could supply continuous electricity even in darkness. It would be especially valuable at the south pole, where permanent shadows hide water-ice deposits. These ice reserves are essential for life support and fuel, so steady power there would expand mission capabilities. Strategically, deploying a reactor would help secure key territory.

China and Russia plan to build one by the mid-2030s, and U.S. officials warn the first country to do so could effectively claim that region, creating a de facto “keep-out zone”. Duffy even called the south pole the Moon’s “best” spot—rich in ice and sunlight—and said America must “get there first and claim that for America”.

Challenges

The directive sets near-term milestones. NASA must appoint a lunar reactor program manager within 30 days and solicit industry proposals within 60 days. The aim is a flight-ready 100 kW reactor by roughly 2030.

However, the plan faces major hurdles. The 2026 budget would allocate about $350 million to jump-start lunar fission power (rising to $500 M by 2027), but also proposes deep cuts to overall NASA funding. Observers note this would be NASA’s smallest budget in decades. Meanwhile, the agency is trimming science programs and even its workforce.
