Off the coast of Hawaii’s Big Island and more than 3,000 feet beneath the ocean surface lie the warm, bubbling springs of a volcano — a deep-sea location that may hold lessons for the search for extraterrestrial life.

NASA's InSight lander has made its first course correction toward Mars.

When low- to middleweight stars like our Sun approach the end of their life cycles they eventually cast off their outer layers, leaving behind a dense, white dwarf star. These outer layers became a massive cloud of dust and gas, which is characterized by bright colors and intricate patterns, known as a planetary nebula. Someday, our Sun will turn into such a nebula, one which could be viewed from light-years away. 

Engineers working with NASA's Curiosity Mars rover have been hard at work testing a new way for the rover to drill rocks and extract powder from them. This past weekend, that effort produced the first drilled sample on Mars in more than a year.

It is springtime in the Northern hemisphere. Countless buds that have been waiting patiently on the stems and branches of trees and shrubs are now blossoming into life. The cosmic equivalent of this season is the time between a few hundred million and a billion years after the Big Bang. This is when the first stars and galaxies ignited, spewing light into the dark universe.

Fast Radio Bursts (FBRs) have fascinated astronomers ever since the first one was detected in 2007. This event was named the “Lorimer Burst” after it discoverer, Duncan Lorimer from West Virginia University. In radio astronomy, this phenomenon refers to transient radio pulses coming from distant cosmological sources, which typically last a few milliseconds on average.

NASA’s next planet hunter, the Transiting Exoplanet Survey Satellite (TESS), is one step closer to searching for new worlds after successfully completing a lunar flyby on May 17. The spacecraft passed about 5,000 miles from the Moon, which provided a gravity assist that helped TESS sail toward its final working orbit.

Researchers have found the strongest evidence yet to suggest that Europa, one of Jupiter’s moons, has plumes ejecting water from its subsurface into space.

Astronomers have used observations from the Atacama Large Millimeter/submillimeter Array (ALMA) and ESO’s Very Large Telescope (VLT) to determine that star formation in the very distant galaxy MACS1149-JD1 started at an unexpectedly early stage, only 250 million years after the Big Bang.

Galileo Galilei discovered Jupiter's moon Europa in 1610. More than four centuries later, astronomers are still making discoveries about its icy surface. With a diameter of almost 2,000 miles, an orbit equivalent to 3.5 Earth days and a mass about 65 percent of Earth's Moon, Europa is considered by some scientists a likely place to look for present-day environments suitable for life.

Earlier this year, astronomers stumbled upon a fascinating finding: Thousands of black holes likely exist near the center of our galaxy.

At present, there are over a dozen robotic missions exploring the atmosphere and surface of Mars. These include, among others, the Curiosity rover, the Opportunity rover, the Mars Orbiter Mission (MOM), the Mars Reconnaissance Orbiter (MRO), the Mars Atmosphere and Volatile EvolutioN (MAVEN) orbiter, and the soon-to-arrive InSight Lander. In the coming decade, many more missions are planned.

NASA will host a Science Chat at 1 p.m. EDT Monday, May 14, to discuss the latest analysis of Jupiter’s moon Europa and its status as one of the most promising places in the solar system to search for life

Though close to home, the space immediately around Earth is full of hidden secrets and invisible processes. In a new discovery reported in the journal Nature, scientists working with NASA’s Magnetospheric Multiscale spacecraft — MMS — have uncovered a new type of magnetic event in our near-Earth environment by using an innovative technique to squeeze extra information out of the data.

Astronomers have discovered evidence for thousands of black holes located near the center of our Milky Way galaxy using data from NASA’s Chandra X-ray Observatory.

A new, incredibly powerful camera called DARKNESS can take pictures of planets close to bright, nearby stars that would normally obscure them.
