Scientists have created a communication network entirely based on light that enables seamless connectivity across space, air, and underwater environments. The new network design combines different types of light sources to ensure connectivity no matter the environment.

“In today’s world, data transmission is critical for communication, navigation, emergency response, research, and commercial activities,” said research team leader Yongjin Wang from Nanjing University of Posts and Telecommunications and Suzhou Lighting Chip Monolithic Optoelectronics Technology Co. Ltd., both in China. “This new wireless network enables uninterrupted connectivity across environments, facilitating two-way real-time data transmission between the network nodes that carry out communication and data exchange within and between networks.”

Using data from the Stratospheric Observatory for Infrared Astronomy (SOFIA) – a joint project of NASA and Germany’s space agency – scientists have, for the first time, discovered water molecules on the surface of an asteroid. A team of researchers looked at four silicate-rich asteroids using an instrument known as Faint Object infraRed CAmera for the SOFIA Telescope (FORCAST), which isolated the mid-infrared spectral signatures indicating molecular water on two of them.

Researchers at the US Southwest Research Institute (SwRI) have developed camera-based autonomous driving tools that can work without deploying technologies like LIDAR and RADAR.

The technology can potentially deliver stealth capabilities for the military while finding applications in space and agriculture.

Modern autonomous driving solutions rely extensively on light detection and ranging (LIDAR) sensors to visualize objects around the vehicle. A software solution then identifies the objects nearby and helps the vehicle’s computer decide whether to halt or slow down.

A critical molecule for the metabolism of living organisms has been synthesized for the first time by University of Hawaiʻi at Mānoa researchers at low temperatures (10 K) on ice coated nanoparticles mimicking conditions in deep space, marking a “cool” step in advancing our understanding of the origins of life.

We know that there are thousands of exoplanets out there, with many millions more waiting to be discovered. But the vast majority of exoplanets are simply uninhabitable. For the few that may be habitable, we can only determine if they are by examining their atmospheres. LIFE, the Large Interferometer for Exoplanets, can help.

Sourabh Shubham: “This area of Mars is known to have a wide variety of hydrated minerals spanning a long stretch of Martian history. A volcanic setting for these minerals had long been suspected. So, it may not be too surprising to find a volcano here. In some sense, this large volcano is a long-sought ‘smoking gun’.”

The planet Mars is known for its vast array of inactive shield volcanoes, and a new volcano could be added to the family with a recent study presented at the 55th Lunar and Planetary Science Conference, as a team of researchers announced the discovery of a massive volcano on Mars that is buried underneath the surface and could even possess a base comprised of glacier ice. This study holds the potential to help scientists better understand past volcanism and glaciation on the Red Planet that could provide clues to Mars’ geologic history.

For the study, the researchers used images from the High Resolution Imaging Science Experiment (HiRISE) camera and data from the Compact Reconnaissance Imaging Spectrometer for Mars (CRISM), which are both onboard NASA’s Mars Reconnaissance Orbiter (MRO), along with data from the Mars Orbiter Laser Altimeter (MOLA) that was onboard the Mars Global Surveyor to analyze “Noctis Mons” (official name pending), which is located southeast of Mars’ Tharsis volcanic region and in the western region of Valles Marineris, known as the largest and deepest canyon in the solar system.

There are so many investments that we could be making, but there are also Moonshots.

Breakthrough discovery puts astronomers one step closer to solving the mystery of the origin of elements that are heavier than iron. An international team of astronomers — including Clemson University astrophysicist Dieter Hartmann — obtained observational evidence for the creation of rare heavy elements in the aftermath of a cataclysmic explosion triggered by the merger of two neutron stars.

The massive explosion unleashed a gamma-ray burst, GRB230307A, the second brightest in 50 years of observations and about 1,000 times brighter than a typical gamma-ray burst. GRB230307A was first detected by NASA’s Fermi Gamma-Ray Space Telescope on March 7, 2023.

Using multiple space-and ground-based telescopes, including NASA’s James Webb Space Telescope, the largest and most powerful telescope ever launched into space, scientists were able to pinpoint the source of the gamma-ray burst in the sky and track how its brightness changed.
