This image from the NASA/ESA/CSA James Webb Space Telescope features an H II region in the Large Magellanic Cloud (LMC), a satellite galaxy of our Milky Way. This nebula, known as N79, is a region of interstellar atomic hydrogen that is ionized, captured here by Webb’s Mid-InfraRed Instrument (MIRI).

N79 is a massive star-forming complex spanning roughly 1,630 light-years in the generally unexplored southwest region of the LMC. N79 is typically regarded as a younger version of 30 Doradus (also known as the Tarantula Nebula), another of Webb’s recent targets. Research suggests that N79 has a star formation efficiency exceeding that of 30 Doradus by a factor of two over the past 500,000 years.

This particular image centers on one of the three giant molecular cloud complexes, dubbed N79 South (S1 for short). The distinct “starburst” pattern surrounding this bright object is a series of diffraction spikes. All telescopes that use a mirror to collect light, as Webb does, have this form of artifact that arises from the design of the telescope.

Germany has built a passive radar demonstrator that tracks targets using radiation from Starlink satellites opportunistically.

The research project demonstrated a power output of 20 watts using a fiber-optic laser and aims to increase this to kilowatts in the future.

The main goal of the WiPTherm project was to create an innovative wireless energy transfer system that could recharge energy storage components on micro and nano-sized satellites.

The IFIMUP was tasked with developing thermoelectric sensors capable of absorbing light at 1,550 nm and using them to charge energy storage devices.

After three years of work, the consortium tested their technologies at the São Jacinto airbase in Aveiro, a city on the Portuguese west coast. During this display, the research team succeeded in generating 20 watts of power output using a fiber optic laser and directed it to the sensors.

WASHINGTON — The Space Development Agency announced Jan. 16 it selected L3Harris, Lockheed Martin and Sierra Space to build and operate 54 satellites equipped with infrared sensors capable of tracking hypersonic missiles in all phases of flight.

The satellites will be part of SDA’s Tranche 2 Tracking Layer, a network of satellites in low orbit 1,000 kilometers above Earth.

The three agreements are worth about $2.5 billion. Each company will produce and operate 18 satellites — the contract awarded to L3Harris is worth $919 million, Lockheed Martin’s is $890 million and Sierra Space’s is $740 million. The contracts include incentives for on-time delivery.

Solar energy is traditionally known for using massive solar panels that collect sunlight and convert it into clean energy, but what if this same energy was instead beamed from satellites in orbit around the Earth, known as space solar power? This is the goal of Space Solar Power Demonstrator (SSPD-1), which is a 110-pound (50-kilogram) project run by the California Institute of Technology (Caltech). SSPD-1 was launched onboard the SpaceX Transporter-6 mission on January 3, 2023, and recently concluded its mission after conducting a series of experiments, including the ability to wirelessly beam solar power from space to Earth, which it accomplished in early 2023.

“Solar power beamed from space at commercial rates, lighting the globe, is still a future prospect. But this critical mission demonstrated that it should be an achievable future,” said Dr. Thomas F. Rosenbaum, who is the President of Caltech and the Sonja and William Davidow Presidential Chair and professor of physics.

SSPD-1 successfully demonstrated three experiments during its one-year mission: DOLCE (Deployable on-Orbit ultraLight Composite Experiment), ALBA, and MAPLE (Microwave Array for Power-transfer Low-orbit Experiment). DOLCE demonstrated the architecture necessary for developing space solar power, ALBA demonstrated how to harness solar energy in space, and MAPLE demonstrated how this energy could be wirelessly beamed to Earth.

The company behind the Dream Chaser spaceplane and the Orbital Reef space station has been selected by the space development agency to build 18 satellites for the tranche 2 tracking layer.

Through exquisite, millimeter-scale, formation flying, the dual satellites making up ESA’s Proba-3 will accomplish what was previously a space mission impossible: Cast a precisely held shadow from one platform to the other, in the process blocking out the fiery sun to observe its ghostly surrounding atmosphere on a prolonged basis.

Ahead of the Proba-3 pair launching together later this year, the scientists who will make use of Proba-3 observations were able to see the satellites with their own eyes. Members of this team will test hardware developed for the mission during an actual terrestrial solar eclipse over northern America next April.

The two satellites are currently undergoing final integration in the premises of Redwire near Antwerp in Belgium. They were paid a visit by the Proba-3 Science Working Team, a 45-strong group of solar physicists coming from all across Europe and the wider world.

Thousands of satellites have been launched into Earth orbit over the past decade or so, with tens of thousands more planned in coming years. Many of these will be in “mega-constellations” such as Starlink, which aim to cover the entire globe.

These bright, shiny satellites are putting at risk our connection to the cosmos, which has been important to humans for countless millennia and has already been greatly diminished by the growth of cities and artificial lighting. They are also posing a problem for astronomers – and hence for our understanding of the universe.

In new research accepted for publication in Astronomy and Astrophysics Letters, we discovered Starlink satellites are also “leaking” radio signals that interfere with radio astronomy. Even in a “radio quiet zone” in outback Western Australia, we found the satellite emissions were far brighter than any natural source in the sky.

Recent regional space developments also include South Korea’s spy satellite launching aboard SpaceX amid North Korea’s surveillance satellites deployment.

The first text exchange was achieved just six days after the satellite launch.

The Starlink team successfully sent and received their first text messages using T-Mobile network spectrum through their new Direct to Cell satellites launched six days prior.
