A White Dwarf Living on the Edge
Astronomers have discovered the smallest and most massive white dwarf ever seen. The smoldering cinder, which formed when two less massive white dwarfs merged, is about 4,300 kilometers across, or somewhat larger than Earth's moon. Though the white dwarf is small, it is heavy, "packing a mass greater than that of our sun into a body about the size of our moon," says Ilaria Caiazzo, the Sherman Fairchild Postdoctoral Scholar Research Associate in Theoretical Astrophysics at Caltech and lead author of the new study appearing in the July 1 issue of the journal Nature.

’A universal definition of space sustainability is hard to find’
Under a new rating system, it will soon be possible to assess the social, economic and environmental impact of space missions. The consortium behind the initiative, which includes the World Economic Forum (WEF), has tasked EPFL's Space Center (eSpace) with finalizing the assessment criteria and implementing the system in this fast-changing field.

Cosmic dawn occurred 250 to 350 million years after Big Bang
Cosmic dawn, when stars formed for the first time, occurred 250 million to 350 million years after the beginning of the universe, according to a new study led by researchers at UCL and the University of Cambridge. The study, published in the Monthly Notices of the Royal Astronomical Society , suggests that the NASA James Webb Space Telescope (JWST), scheduled to launch in November, will be sensitive enough to observe the birth of galaxies directly.

Dark Energy Survey Releases Most Precise Look at the Universe’s Evolution
Carnegie Mellon University New results from the Dark Energy Survey (DES) used the largest ever sample of galaxies over an enormous piece of the sky to produce the most precise measurements of the universe's composition and growth to date. Scientists measured that the way matter is distributed throughout the universe is consistent with predictions in the standard cosmological model, the best current model of the universe.

Edge of Pine Island Glacier's ice shelf is ripping apart, causing key Antarctic glacier to gain speed
Edge of Pine Island Glacier’s ice shelf is ripping apart, causing key Antarctic glacier to gain speed
The ice shelf on Antarctica's Pine Island Glacier lost about one-fifth of its area from 2017 to 2020, mostly in three dramatic breaks. The timelapse video incorporates satellite images from January 2015 to March 2020. For most of the first two years, the satellite took high-resolution images every 12 days; then for more than three years it captured images of the ice shelf every six days.

Cause, scope determined for deadly winter debris flow in Uttarakhand, India
The Uttarakhand region of India experienced a humanitarian tragedy on Feb. 7, 2021, when a wall of debris and water barreled down the Ronti Gad, Rishiganga and Dhauliganga river valleys. The event began when a wedge of rock carrying a glacier broke off of a steep ridge in the Himalayan mountain range.

Is Earth’s core lopsided? Strange goings-on in our planet’s interior
A new model by UC Berkeley seismologists proposes that Earth's inner core grows faster on its east side (left) than on its west. Gravity equalizes the asymmetric growth by pushing iron crystals toward the north and south poles (arrows). This tends to align the long axis of iron crystals along the planet's rotation axis (dashed line), explaining the different travel times for seismic waves through the inner core.

Gravitational wave search no humdrum hunt
The hunt for the never before heard "hum" of gravitational waves caused by mysterious neutron stars has just got a lot easier, thanks to an international team of researchers. Gravitational waves have only been detected from black holes and neutron stars colliding, major cosmic events that cause huge bursts that ripple through space and time.

Do lightning storms affect high-flying satellites?
The VIPER experiment was aboard this sounding rocket when it was launched at 9:15 p.m. EDT on Wednesday, May 26, 2021, from Wallops Flight Facility in Virginia. (Photo courtesy of NASA) Lightning storms produce bursts of radio waves called whistlers that seem innocuous as they bounce off the ionosphere and dissipate with seemingly little effect.
