A team of University of Florida researchers used the James Webb Space Telescope to capture photos of a star-forming region known as W51 with never-before-seen clarity and resolution. The long wavelengths of JWST’s infrared technology allowed astronomers to see the stars clearly and show what was previously hidden. Stars in the W51 region are very young and massive, and using the telescope gave the team the ability to view the early stages of star formation.
With NASA preparing for the Artemis II launch (expected tomorrow, 1 April), a strong solar flare earlier this week is putting space weather back into focus—and highlighting the unpredictable risks astronauts could face beyond Earth’s atmosphere. Professor Keith Ryden, leader of the Space Environment and Protection research team at the Surrey Space Centre, University of Surrey, has shared new insights into what this flare means for the mission, and why events like this remain difficult to predict.His comment also includes historical context from Visiting Professor at Surrey Space Centre, Clive Dyer, who worked on the Apollo program:
The man pulled the gun from beneath his clothing and pointed it at a Phoenix Police officer as he fled, prompting officers to fire shots
The armed suspect barricaded himself with two women and shot an officer before being fatally shot by SWAT
Astronomers from Egypt and Turkey have conducted a comprehensive analysis of kinematic, structural, and astrophysical parameters of a nearby open cluster known as NGC 2168. Results of the new study, published March 23 on the arXiv preprint server, put more constraints on the properties of this cluster.
Less than two days from now, NASA’s Artemis II mission is scheduled to lift off for its historic 10-day journey around the moon, marking the first time humans have ventured beyond Low Earth Orbit for the first time since Apollo 17 in 1972, and possibly even set new distance records for traveling beyond Earth. However, Artemis II is only scheduled as a flyby mission and will not be landing humans on the lunar surface, with this endeavor being scheduled for later missions.
Monash University researchers have captured the exact atomic movements that write data to next-generation memory devices, which could pave the way for smaller, faster and more energy-efficient electronics. Published in Nature Communications, the study was led by Dr. Kousuke Ooe, a Japan Society for the Promotion of Science (JSPS) postdoctoral fellow in the School of Physics and Astronomy at Monash University who is first author of the paper, in collaboration with Australian Laureate Professor Joanne Etheridge and researchers from the Japan Fine Ceramics Center, Kyoto University, and the University of Osaka.
In case of an emergency, the Federal Aviation Administration requires aircraft to be able to evacuate within 90 seconds. However, as the median age of the global population increases, the growing number of elderly airline passengers poses new challenges during emergency situations.
The Fresno City Council changed city law to allow officers to enter areas of private property considered public without a warrant for code enforcement purposes
Whenever humans arrive on Mars, they’re going to find it a difficult place to exist. Mars is cold, with an average surface temperature of -55°C; temperatures can plunge to -125°C with dust storms lasting months; its atmosphere is very thin and almost all carbon dioxide; and all the water is frozen and mixed with ice made of CO2. Oh, and solar radiation will be hazardous on Mars’ surface since the planet has no ozone layer to block ultraviolet radiation, especially so during solar flares. Disneyland it is not.
It’s humanity’s first flight to the moon since 1972.
Utilizing the stellar evolution code named Modules for Experiments in Stellar Astrophysics (MESA), Chinese astronomers have investigated the evolution of a recently discovered ultra-compact double white dwarf binary system known as ATLAS J1138-5139. Results of this study, published March 20 on the arXiv pre-print server, allowed the researchers to determine the fate of this system.
As soon as Wednesday, NASA is poised to make history—sending the first woman, the first person of color, and the first non-American on a voyage around the moon.
NASA began the countdown Monday for humanity’s first launch to the moon in 53 years.
Planetary surface missions currently operate cautiously. On Mars, communication delays between Earth and rovers (typically between four and 22 minutes), as well as data transfer constraints due to uplink and downlink limitations, force scientists to plan operations in advance. Rovers are designed for energy efficiency and safety, and to move slowly across hazardous terrain.
