Lunar eclipse: Tips for watching the eclipse
- Tips for watching the lunar eclipse include checking the date and time, finding a dark sky location, and taking warm clothes and blankets for a comfortable viewing experience.
- To capture the stages of a total lunar eclipse, observe the penumbral eclipse, partial eclipse, and totality phase when the moon is completely covered by Earth's shadow.
- During totality, the moon may appear red or display colors like oranges, coppers, grays, and browns, creating a mesmerizing visual effect.
- The greatest eclipse, marked by the shadow on the moon, can reveal three-dimensional features and unique colors influenced by factors like volcanic eruptions on Earth.
- After totality, the inner umbral shadow leaves the moon, signaling the end of the eclipse, followed by the departure of the outer penumbral shadow.
- Rare phenomenon called selenelion, where the eclipsed moon and the sun can be seen simultaneously due to atmospheric refraction, may be observed from specific locations on Earth.
- For photographing the lunar eclipse, share images on EarthSky Community Photos and be aware of the key stages of the eclipse to capture its progression successfully.
- Make sure to plan your eclipse viewing in a location with unobstructed views of the sky, such as city or state parks, for an optimal experience.
- Understanding the celestial geometry and atmospheric effects can enhance the appreciation of the eclipse phenomena, such as the gradual dimming of Earth's surroundings during totality.
- Consider visiting EarthSky's Best Places to Stargaze for recommendations on prime eclipse-viewing locations and to enjoy the wonders of the night sky.
- Appreciate the beauty and scientific significance of a total lunar eclipse by immersing yourself in its various phases and marveling at the cosmic dance of Earth, the moon, and the sun.

Narwhals play and forage using their amazing tusks
- Narwhals in the Canadian High Arctic use their tusks for various activities such as foraging, exploration, and play, as shown in drone footage clips.
- Researchers have used drones to gain insights into narwhal behavior, revealing how they target prey like Arctic char and engage in social behaviors.
- Narwhals, known as unicorns of the sea, are primarily fish-eaters living in the frigid Arctic waters of Canada, Greenland, and Russia.
- The narwhal tusk, a spiral-shaped tooth, grows continuously throughout their life and can reach lengths of up to 10 feet.
- The tusks, possessing numerous nerves, also act as environmental sensors detecting water temperature and salinity.
- Drone footage captured by researchers revealed narwhals wielding their tusks with agility to investigate and target prey like Arctic char.
- Narwhals were observed using their tusks for play-like behavior, exploring objects like fish, and potentially exhibiting distinct personality traits.
- Scientists noted the collaborative and possibly competitive behavior of narwhals using their tusks to interact with fish, including attempts to block others' access to prey.
- Using drones to study narwhals offers a non-invasive method to understand their behavior and adaptability in response to environmental changes like climate change.
- By observing narwhals in their natural environment without disturbance, researchers can gather crucial data on their responses to shifts in ice patterns and prey availability.

NASA Launches Missions to Study Sun, Universe’s Beginning
- NASA launched the SPHEREx and PUNCH missions on March 11, 2025, to study the Sun and the universe's beginning.
- SPHEREx will explore our universe's origins, the history of galaxies, and the search for life's building blocks.
- PUNCH will investigate how the Sun's outer atmosphere transforms into the solar wind.
- Both missions, launched on a single rocket, aim to enhance our understanding of the cosmos.
- SPHEREx will produce a 3D map of the sky every six months and study 450 million nearby galaxies.
- The mission will also search for hidden frozen water ice and molecules essential for life in our galaxy.
- PUNCH will make 3D observations of the solar system and study space weather events to protect spacecraft and astronauts.
- The missions will operate in low Earth orbit to shield SPHEREx's telescope from the Sun's interference.
- SPHEREx's data will be publicly available for scientific analysis and will probe questions about the universe's origins and potential for life beyond Earth.
- PUNCH aims to shed light on how solar winds and space weather impact Earth and spacecraft in the inner solar system.

Galactic ‘Sloshing’: How cosmic collisions keep galaxy clusters hot
- Scientists have discovered that gas inside galaxy clusters moves like liquid in a shaken cup, keeping the clusters warm.
- The XRISM satellite measured the speed of hot gas in the Centaurus Cluster, revealing large-scale gas flows caused by collisions between clusters.
- The collisions create a 'sloshing' effect, constantly stirring and redistributing energy, which prevents the gas from cooling down.
- This discovery provides new insights into how galaxy clusters evolve and stay active, supporting the role of mergers and interactions in shaping the universe.
