The core of our Milky Way is buzzing with stars. Recently astronomers reported that it contains at least one ancient star that formed outside our galaxy. Now, an international research team reports finding a grouping of very young ones there, as well. Their presence upends ideas about star birth in that densely packed region of space.

Video: 00:05:47
Ice is without doubt one of the first casualties of climate change, but the effects of our warming world are not only limited to ice melting on Earth’s surface. Ground that has been frozen for thousands of years, called permafrost, is thawing – adding to the climate crisis and causing serious issues for local communities.

Why Was it Tricky to Know the Distances to Galaxies JWST Was Seeing?
One of the chief objectives of the James Webb Space Telescope (JWST) is to study the formation and evolution of the earliest galaxies in the Universe, which emerged more than 13 billion years ago. To this end, scientists must identify galaxies from different cosmological epochs to explore how their properties have changed over time. This, in turn, requires precise dating techniques so astronomers are able to determine when (in the history of the Universe) an observed galaxy existed. The key is to measure the object’s redshift, which indicates how long its light has been traveling through space.
Psyche Gives Us Its First Images of Space
NASA’s Psyche mission began eight weeks ago when it launched from the Kennedy Space Center. While it won’t reach its objective, the metal-rich asteroid Psyche, until 2029, the spacecraft has already travelled 26 million km (16 million miles.) During that time, it’s already had its share of success as it ticks off items on its checklist of tests.
