Over the course of our existence, humanity has struggled to definitively answer the question: “Are we alone?”

Is Earth the only planet in the vast cosmic sea that contains life? As our technology becomes more advanced, we get closer and closer to the answer.

Our solar system contains a multitude of worlds, planetary bodies ranging from ice planets to gas giants with magnificent rings to rocky, terrestrial worlds like our own. But what lies out beyond our stellar neighborhood?

It’s only been in the last few decades that scientists have detected planets orbiting other stars. We call them exoplanets. Since that initial discovery, researchers have trained their telescopes on the cosmos in search of new and different worlds.

Their efforts were not in vain, as thousands of exoplanets have been detected. Now, scientists are starting to shift their focus to the individual planets and learning as much as they can about them. Do they contain life? What are they made of? What kind of atmosphere do they have?

These are the types of questions we hope to answer about the alien worlds that fill our universe.

One element essential to life on Earth is oxygen. Its presence is what scientists refer to as a biosignature. (These are the types of things NASA’s next Mars rover will look for.) A recent paper published in Nature Astronomy details a new technique that scientists are hoping will help them detect the presence of oxygen in exoplanet atmospheres.

Like methane, oxygen is a biosignature but its presence does not guarantee we will find life. There are plenty of non-biological processes that produce oxygen (as well as methane). However, if other biosignatures are detected in addition to oxygen, the chances of life increase significantly.

NASA’s Curiosity rover detected a methane cycle on Mars that varies with the seasons. However, its orbital counterparts — European spacecraft TGO and Mars Express — have not. The science team is working to identify what is causing the methane spikes as well as why it seems to disappear as it rises through the atmosphere.

“Oxygen is one of the most exciting molecules to detect because of its link with life, but we don’t know if life is the only cause of oxygen in an atmosphere,” Edward Schwieterman, an astrobiologist at UC Riverside and co-author on the study, said in a statement. “This technique will allow us to find oxygen in planets both living and dead.”

The new method was developed by a team led by Thomas Fauchez, a planetary scientist at NASA’s Goddard Space Flight Center. It is derived from the behavior of oxygen molecules in Earth’s atmosphere.

When oxygen molecules collide, they produce a signala very subtle dip in infrared radiation. Unfortunately, that signal is so faint that current observatories cannot detect it in distant planets. But that will soon change. NASA’s latest and greatest telescope, the James Webb Space Telescope (JWST) will come online sometime in the next few years. Fauchez’s team has shown that JWST, which will observe the universe in the infrared, should have what it takes to spot it.

“Before our work, oxygen at similar levels as on Earth was thought to be undetectable with Webb,” said Fauchez in a statement. “This oxygen signal is known since the early 1980s from Earth’s atmospheric studies but has never been studied for exoplanet research.”

In the meantime, NASA’s Mars 2020 rover will launch to the red planet in July. Once it’s on Mars, it will study Jezero Crater, the site of an ancient river delta and scan the region for signs of life (like oxygen, methane, and other biosignatures). The rover will also bag up bits of Mars to be returned to Earth at a later date.

SpaceX’s Starlink Router Mini targets home Wi-Fi dead zones for $40

The Starlink Router Mini tackles home Wi-Fi dead zones for just $40. Compact & mesh-compatible, it’s built for basic setups.

SpaceX’s Starlink Router Mini recently launched to enhance home Wi-Fi connectivity by addressing dead zones at home, offering a budget-friendly option for customers. The Starlink Router Mini is a $40 mesh-compatible device.

The Router Mini targets users seeking affordable solutions to extend coverage in smaller spaces. SpaceX describes the new Starlink router as a lower-performance device suited for “basic Wi-Fi needs” in compact setups.

“It works well in most basic residential setups and is a good option for extending coverage. However, in homes where rooms have multiple barriers between them (mirrors, multiple walls, brick or stone walls), you may notice a drop in performance unless you use wired connections,” the company noted.

In contrast, the Gen 3 router, now priced at $120 after dropping from $199, delivers stronger performance for larger homes with multiple devices. The Router Mini complements the Gen 3 router, which comes bundled with the standard Starlink dish and supports mesh networking.

“If you need simple, reliable Wi-Fi and want to keep costs down, the Router Mini is a solid option. But if you’re looking for stronger, more consistent performance across a larger or busier home, the Gen 3 Router is the way to go,” SpaceX explained.

Both routers support Wi-Fi 6 speeds and can operate in wired or wireless mesh modes, though the dual-band Starlink Router Mini has fewer antennas (“2×2 2.4 GHz, 2×3 5 GHz MU-MIMO”) compared to the tri-band Gen 3’s four-plus antenna setup.

The Router Mini’s debut follows its appearance in an FCC filing and a Starlink app update referencing a “mini mesh” device. It also connects to the Starlink Mini dish, boosting its limited Wi-Fi range. The device’s affordability and mesh compatibility make it an attractive option for customers looking to optimize their Starlink setup without investing in additional Gen 3 routers.

As Starlink continues to expand its global broadband network, the Router Mini addresses growing demand for flexible, cost-effective home connectivity solutions. By offering a cheaper mesh device, SpaceX strengthens its ecosystem, catering to diverse user needs while maintaining its lead in satellite internet innovation.

SpaceX secures FAA approval for 25 annual Starship launches

SpaceX scored FAA approval for up to 25 Starship launches annually. The agency found no major environmental impact, but critics remain skeptical.

SpaceX secured Federal Aviation Administration (FAA) approval to launch and land Starship rockets and Super Heavy boosters from its Starbase spaceport in Boca Chica, Texas, up to 25 times a year. The FAA’s decision was announced on Tuesday, marking a pivotal step for SpaceX’s ambitious space exploration goals.

The FAA’s SpaceX approval is part of its ongoing license review. The agency noted that “there are other licensing requirements still to be completed,” including evaluations of policy, payload, safety, financial responsibility, and environmental impacts.“Once the evaluation process is complete, the FAA will make a determination to approve or deny the license application,” the agency added.

The FAA’s final environmental assessment concluded that SpaceX’s expanded launch plans would have “no significant impact” on the surrounding environment, defying a history of legal disputes with environmental groups.

The ruling follows a significant weekend for Starbase, where residents—mostly SpaceX employees—voted to incorporate the area as a city. Starbasee City includes a mayor and two commissioners from the aerospace company’s ranks. The FAA’s decision amplifies SpaceX’s momentum but has sparked concerns among environmentalists.

Christopher Basaldu of the South Texas Environmental Justice Network called the environmental assessment premature.

“You’re bragging about the big slot rocket in history, and then you’re also trying to claim that it makes no environmental impact; that’s impossible. So they’re lying. So what the FAA needs to do is they need to go all the way back to square one,” Basaldu said.

Basaldu highlighted potential harm to marine life, pollution risks to the nearby Rio Grande, and disruptions from noise and night operations coming from SpaceX launches.

“A lot of noise pollution. That’s not a lot of night pollution, because they try to continue working through the night, while SpaceX is going to shut down the road for half of the year.”

As SpaceX pushes to scale Starship operations, the FAA’s approval underscores Starbase’s growing role in space exploration. However, ongoing environmental reviews and local concerns signal challenges ahead, balancing innovation with ecological and community impacts.
