Mysterious red spots on Mercury get names – but what are they?
Mercury is the closest planet to the sun, but far from being a dull cinder of a world, it has instead turned out to be a real eye opener for geologists. Among the revelations by NASA's MESSENGER probe, which first flew past Mercury in 2008 and orbited it between 2011 and 2015, is the discovery of a hundred or so bright red spots scattered across the globe. Now they are at last being named.

Is dark matter made of primordial black holes?
Astronomers studying the motions of galaxies and the character of the cosmic microwave background radiation came to realize in the last century that most of the matter in the universe was not visible. About 84 percent of the matter in the cosmos is dark matter, much of it located in halos around galaxies. It was dubbed dark matter because it does not emit light, but it is also mysterious: it is not composed of atoms or their usual constituents like electrons and protons.

Stars are born in loose groupings
Based on previously published data from the Gaia Mission, researchers at Heidelberg University have derived the conditions under which stars form. The Gaia satellite is measuring the three-dimensional positions and motions of stars in the Milky Way with unprecedented accuracy. Using these data, Dr. Jacob Ward and Dr. Diederik Kruijssen determined the positions, distances and speeds of a large number of young massive stars within 18 nearby loose stellar groupings. The researchers were able to demonstrate that there is no evidence whatsoever that these associations are expanding. They therefore could not have originated as a dense cluster and then expanded to their current size.

The challenges of an alien spaceflight program—escaping super-Earths and red dwarf stars
Since the beginning of the Space Age, humans have relied on chemical rockets to get into space. While this method is certainly effective, it is also very expensive and requires a considerable amount of resources. As we look to more efficient means of getting out into space, one has to wonder if similarly advanced species on other planets (where conditions would be different) would rely on similar methods.

Simulations suggest Saturn may have helped create Jupiter's big moons
A team of researchers from France and the U.S. has created a computer simulation of the development of the solar system focusing on Jupiter and the origins of its moons. In their paper uploaded to the arXiv preprint server, the group describes the simulation showing that Saturn may have played a role in the creation of Jupiter's largest moons.

New research seeks to optimize space travel efficiency
Sending a human into space and doing it efficiently presents a galaxy of challenges. Koki Ho, University of Illinois assistant professor in the Department of Aerospace Engineering, and his graduate students, Hao Chen and Bindu Jagannatha, explored ways to integrate the logistics of space travel by looking at a campaign of lunar missions, spacecraft design, and creating a framework to optimize fuel and other resources.

Martian moons model indicates formation following large impact
Southwest Research Institute scientists posit a violent birth of the tiny Martian moons Phobos and Deimos, but on a much smaller scale than the giant impact thought to have resulted in the Earth-Moon system. Their work shows that an impact between proto-Mars and a dwarf-planet-sized object likely produced the two moons, as detailed in a paper published today in Science Advances.

Thinking about hitching a ride on a mission to Mars? One hazard you haven't considered
The hazards of space flight are well known: freezing temperatures, the vacuum of space, radiation, isolation. But there's a lesser-known risk getting the attention of researchers - a possible danger to vision. Retired NASA astronaut David Wolf, M.D., will provide insight into how space flight affects the eye on Thursday, April 19, when he gives the keynote address during a conference attended by many of the nation's leading eye physicians and surgeons, hosted by the American Academy of Ophthalmology in Washington, D.C.

Could we detect an ancient industrial civilization in the geological record?
As a species, we humans tend to take it for granted that we are the only ones that live in sedentary communities, use tools, and alter our landscape to meet our needs. It is also a foregone conclusion that in the history of planet Earth, humans are the only species to develop machinery, automation, electricity, and mass communications – the hallmarks of industrial civilization.
