Using the Gran Telescopio Canarias (GTC), astronomers from Italy and Spain have carried out high-temporal-resolution optical spectroscopic observations of a transitional millisecond pulsar designated PSR J1023+0038. Results of the observational campaign, published September 19 on the pre-print server arXiv, yield essential information regarding the nature of this pulsar.

Since the first sighting of the first-discovered and largest asteroid in our solar system was made in 1801 by Giuseppe Piazzi, astronomers and planetary scientists have pondered the make-up of this asteroid/dwarf planet. Its heavily battered and dimpled surface is covered in impact craters. Scientists have long argued that visible craters on the surface meant […]

A study published in Engineering has shed new light on the behavior of lunar regolith particles under the influence of an external electric field, a discovery that could revolutionize space exploration and lunar resource utilization. The research, conducted by a collaborative team of scientists from the Qian Xuesen Laboratory of Space Technology, Tsinghua University, and […]

In May 2024, a geomagnetic storm hit Earth, sending auroras across the planet’s skies in a once-in-a-generation light display. These dazzling sights are possible because of the interaction of coronal mass ejections—explosions of plasma and magnetic field from the sun—with Earth’s magnetic field, which protects us from the radiation the sun spits out during turbulent […]
