A deep reservoir of primordial helium in the Earth
Noble gases, including helium, neon, and argon, are characterized by high chemical inertness which causes low reactivity with other materials and high volatility. Among them, 3He, 20Ne, and 36Ar are particular isotopes which were components of the pr.....»»
NASA to overhaul mission returning samples from Mars—here"s why it must and will go ahead
NASA recently announced that it is seeking new ways to complete the return to Earth of rock cores drilled by the Perseverance Rover in the Jezero Crater on Mars. This has led to some anxiety among space scientists, who view the Mars Sample Return (MS.....»»
Observations explore globular cluster system in the galaxy NGC 4262
Using the Canada-France-Hawaii Telescope (CFHT), Indian astronomers have performed wide and deep field observations of a polar ring galaxy known as NGC 4262. Results of the observational campaign, published April 15 on the pre-print server arXiv, she.....»»

First discovery in decades of blue whales near Seychelles
Blue whales are fascinating animals. At 24–30 meters in length (longer than a basketball court) they are the largest creatures on Earth. They are also among the rarest. Estimates suggest that there are only about 5,000 to 15,000 blue whales left in.....»»
Computer model helps support theory of asteroid Kamo"oalewa as ejecta from the moon
A small international team of planetary scientists has found evidence supporting the theory that the near-Earth asteroid Kamo'oalewa is ejecta from the moon. In their paper published in the journal Nature Astronomy, the group describes their data-dri.....»»
Mangrove blue carbon at higher risk of microplastic pollution
Earth's oceans and coastal ecosystems are a major sink for carbon storage, known as blue carbon. Sequestration of carbon is vitally important in the fight against climate change as it 'locks away' this molecule, alleviating pressure on greenhouse gas.....»»
Secrets of the Octopus takes us inside the world of these “aliens on Earth”

Crucial building blocks of life on Earth can more easily form in outer space, says new research
The origin of life on Earth is still enigmatic, but we are slowly unraveling the steps involved and the necessary ingredients. Scientists believe life arose in a primordial soup of organic chemicals and biomolecules on the early Earth, eventually lea.....»»
Biden unveils winners of $2 billion in green tax credits
Battery-material maker Novonix, electric vehicle charger manufacturer Wallbox and rare earth producer MP Materials Corp. were among about 35 recipients of clean energy tax credits totaling nearly $2 billion that were announced Friday by the Biden adm.....»»
The Italian central Apennines are a source of CO₂, study finds
Tectonically active mountains play an important role in the natural CO2 regulation of the atmosphere. Competing processes take place here: At Earth's surface, erosion drives weathering processes that absorb or release CO2, depending on the type of ro.....»»
AI for Earth: How NASA"s artificial intelligence and open science efforts combat climate change
As extreme weather events increase around the world due to climate change, the need for further research into our warming planet has increased as well. For NASA, climate research involves not only conducting studies of these events, but also empoweri.....»»
"Green muscle memory" and climate education promote behavior change: Report
This year, organizers of Earth Day are calling for widespread climate education as a critical step in the fight against climate change......»»
Weather prediction models can also forecast satellite displacements
New research finds that modern weather models can accurately predict satellite movements due to the energy emitted and reflected by the Earth. In addition to weather prediction, weather models can also help understand and predict how satellites respo.....»»
NASA may alter Artemis III to have Starship and Orion dock in low-Earth orbit
If it were to happen, a revised Artemis III mission could echo Apollo 9. Enlarge / This image taken by NASA's Orion spacecraft shows its view just before the vehicle flew behind the Moon in 2022. (credit: NASA) Although.....»»
Unraveling water mysteries beyond Earth: Ground-penetrating radar will seek bodies of water on Jupiter
Finding water on distant planets and moons in our solar system is a challenge, especially when the instrument is thousands of kilometers away from the surface, but scientists presenting at the European Geosciences Union General Assembly describe how.....»»
Warming of Antarctic deep-sea waters contribute to sea level rise in North Atlantic, study finds
Analysis of mooring observations and hydrographic data suggest the Atlantic Meridional Overturning Circulation deep water limb in the North Atlantic has weakened. Two decades of continual observations provide a greater understanding of the Earth's cl.....»»
Using deep learning to image the Earth"s planetary boundary layer
Although the troposphere is often thought of as the closest layer of the atmosphere to the Earth's surface, the planetary boundary layer (PBL)—the lowest layer of the troposphere—is actually the part that most significantly influences weather nea.....»»
Fallout games continue seeing big player jumps after the TV series’ success
