Image: A chance alignment in Lupus

The subject of today’s NASA/ESA Hubble Space Telescope Picture of the Week is the stunning spiral galaxy NGC 5530. NGC 5530 is situated 40 million light-years away in the constellation Lupus (The Wolf). This galaxy is classified as a “flocculent” spiral, meaning that its spiral arms are patchy and indistinct.

Hubble spots star cluster NGC 346

In anticipation of the upcoming 35th anniversary of the NASA/ESA Hubble Space Telescope, ESA/Hubble is kicking off the celebrations with a new image of the star cluster NGC 346, featuring new data and processing techniques. This prolific star factory is in the Small Magellanic Cloud, one of the largest of the Milky Way’s satellite galaxies.

A mission that could reach Mercury on solar sails alone

Turns out, it’s as tough to drop inward into the inner solar system, as it is to head outward. The problem stems from losing momentum from a launch starting point on Earth. It can take missions several years and planetary flybys before capture and arrival in orbit around Mercury or Venus.

Here’s how we could quickly raise temperatures on Mars

Multiple plans exist to explore Mars in the coming decades using robotic and crewed missions. The ultimate goal of these missions is to determine whether human beings could actually live there someday. This requires access to building materials, water, cutting-edge manufacturing technology, and closed-loop habitation systems with bioregenerative life support systems (BLSS). Basically, future settlers will need to create conditions that mimic Earth’s self-sustaining ecological systems—essentially, we need to “take Earth with us” to other planets.

Hot Schrödinger cat states created

Quantum states can only be prepared and observed under highly controlled conditions. A research team from Innsbruck, Austria, has now succeeded in creating so-called hot Schrödinger cat states in a superconducting microwave resonator. The study, published in Science Advances, shows that quantum phenomena can also be observed and used in less perfect, warmer conditions.

Enhancing heat transfer using the turbulent flow of viscoelastic fluids

Fluids play a crucial role in industrial processes like cooling, heating, and mixing. Traditionally, most industries would utilize Newtonian fluids—which have a constant viscosity—for such processes. However, many are now adopting viscoelastic fluids, which can behave as both liquids and elastic materials.

An exception to the laws of thermodynamics: Shape-recovering liquid defies textbooks

A team of researchers led by a physics graduate student at the University of Massachusetts Amherst made the surprising discovery of what they call a “shape-recovering liquid,” which defies some long-held expectations derived from the laws of thermodynamics.
