SwRI scientist searches for stellar phosphorus to find potentially habitable exoplanets

SAN ANTONIO -- Sept. 16, 2020 -- A Southwest Research Institute scientist has identified stellar phosphorus as a probable marker in narrowing the search for life in the cosmos. She has developed techniques to identify stars likely to host exoplanets, based on the composition of stars known to have planets, and proposes that upcoming studies target stellar phosphorus to find systems with the greatest probability for hosting life as we know it.

SwRI-led study indicates sand-sized meteoroids are peppering asteroid Bennu

A new study published this month in JGR Planets posits that the major particle ejections off the near-Earth asteroid Bennu may be the consequence of impacts by small, sand-sized particles called meteoroids onto its surface as the object nears the Sun. The study's primary author is Southwest Research Institute scientist Dr. William Bottke, who used data from NASA's OSIRIS-REx mission.

SwRI scientist modeled Mars climate to understand habitability

A Southwest Research Institute scientist modeled the atmosphere of Mars to help determine that salty pockets of water present on the Red Planet are likely not habitable by life as we know it on Earth. A team that also included scientists from Universities Space Research Association (USRA) and the University of Arkansas helped allay planetary protection concerns about contaminating potential Martian ecosystems. These results were published this month in Nature Astronomy.

SwRI fire study reveals how country, code variations impact escape time

Southwest Research Institute® (SwRI®) conducted room burn comparisons to better understand how country-specific fire codes in the U.S., France and the United Kingdom affect the fire safety of home furnishings and their contributions to flashover. Reducing the rate for flashover in a room burn can significantly save lives translating to more time for people to escape a fire. Flashover occurs when temperatures at the ceiling reach 1,000 degrees C and all the combustibles in the room ignite.

How a space snowman called Arrokoth is shedding new light on planetary origins

The space snowman that was the focus of a close encounter with NASA's New Horizons probe last year is helping scientists answer a cosmic question: How did the building blocks of the solar system get their start? "This is a game-changer," said Alan Stern, a planetary scientist at the Southwest Research Institute and principal investigator for the New Horizons mission. Stern and other members of the New Horizons science team shared their latest findings about the snowman-shaped object now know...

SwRI models hint at longer timescale for Mars formation

The early solar system was a chaotic place, with evidence indicating that Mars was likely struck by planetesimals, small protoplanets up to 1,200 miles in diameter, early in its history. Southwest Research Institute scientists modeled the mixing of materials associated with these impacts, revealing that the Red Planet may have formed over a longer timescale than previously thought.

SwRI-led team identifies low-energy solar particles from beyond Earth near the Sun

Using data from NASA's Parker Solar Probe (PSP), a team led by Southwest Research Institute identified low-energy particles lurking near the Sun that likely originated from solar wind interactions well beyond Earth orbit. PSP is venturing closer to the Sun than any previous probe, carrying hardware SwRI helped develop. Scientists are probing the enigmatic features of the Sun to answer many questions, including how to protect space travelers and technology from the radiation associated with solar...

New SwRI models reveal inner complexity of Saturn moon

A Southwest Research Institute team developed a new geochemical model that reveals that carbon dioxide (CO2) from within Enceladus, an ocean-harboring moon of Saturn, may be controlled by chemical reactions at its seafloor. Studying the plume of gases and frozen sea spray released through cracks in the moon's icy surface suggests an interior more complex than previously thought.

Satellite evades ‘day of reckoning' to discover puzzling weather phenomenon on Jupiter

At first glance, these newly released images by NASA may look like lava churning in the heart of a volcano, but they reveal otherworldly storm systems whirling in a way that surprised scientists.The swirls in the photos are cyclones around Jupiter's south pole, captured by NASA's Juno spacecraft on Nov. 3, 2019. Juno has been orbiting the solar system's largest planet since 2016 and has seen these polar cyclones before, but its latest flight over this region of the planet revealed a ...

SwRI, international team use deep learning to create virtual 'super instrument'

A study co-written by a Southwest Research Institute scientist describes a new algorithm that combines the capabilities of two spacecraft instruments, which could result in lower cost and higher efficiency space missions. The virtual 'super instrument,' is a computer algorithm that utilizes deep learning to analyze ultraviolet images of the Sun, taken by NASA's Solar Dynamics Observatory, and measure the energy that the Sun emits as ultraviolet light.

New Horizons’ far-out findings from solar system’s Kuiper Belt turn into a cover story

The space snowman known as 2014 MU69 or Ultima Thule added to its celebrity today by showing up on the cover of the journal Science, with the first peer-reviewed results from an encounter with NASA's New Horizons spacecraft laid out within. Close study of the two-lobed object — which orbits 4 billion miles from the sun within a sparse belt of icy material known as the Kuiper Belt — could shed light on how the solar system was formed, said New Horizons principal investigator Alan Stern, a pla...

The Most Distant Object Ever Explored Is Lumpy. And Astronomers Don't Know Why.

Ultima Thule is lumpy, and scientists aren't sure why.Just after midnight on Jan. 1, NASA's New Horizons spacecraft zoomed past Ultima Thule, a small, frigid object that lies about 1 billion miles (1.6 billion kilometers) beyond the orbit of Pluto. The photos New Horizons captured during that epic encounter revealed a world unlike any other ever seen up close. The 21-mile-wide (33 km) Ultima Thule is bilobed and therefore resembles a reddish snowman -- if that snowman had been flattened ...

SwRI engineers develop novel techniques to trick object detection systems

New adversarial techniques developed by engineers at Southwest Research Institute can make objects 'invisible' to image detection systems that use deep-learning algorithms. These techniques can also trick systems into thinking they see another object or can change the location of objects. The technique mitigates the risk for compromise in automated image processing systems.

SwRI-led team identifies water-bearing minerals on asteroid Bennu

A Southwest Research Institute-led team discovered evidence of abundant water-bearing minerals on the surface of the near-Earth asteroid (101955) Bennu. Using early spectral data from NASA's OSIRIS-REx spacecraft orbiting the asteroid, the team identified infrared properties similar to those in a type of meteorite called carbonaceous chondrites.

SwRI-led New Horizons research indicates small Kuiper Belt objects are surprisingly rare

Using New Horizons data from the Pluto-Charon flyby in 2015, a Southwest Research Institute-led team of scientists have indirectly discovered a distinct and surprising lack of very small objects in the Kuiper Belt. The evidence for the paucity of small Kuiper Belt objects (KBOs) comes from New Horizons imaging that revealed a dearth of small craters on Pluto's largest satellite, Charon, indicating that impactors from 300 feet to 1 mile (91 meters to 1.6 km) in diameter must also be rare.

An asteroid will block the sky's brightest star tonight, and astronomers need your help seeing it

Sirius, a system of two stars — Sirius A and Sirius B — is the brightest object we can see from Earth. However, an asteroid called (4388) Jürgenstock will briefly pass in front of Sirius on Monday night. Sirius will almost entirely fade for a few tenths of a second as the 3.1-mile-wide asteroid flies by. The occultation, as it's called, should be visible in parts of Mexico, six US states, and Canada. Sirius, a double-star system and the brightest object in the night sky, will briefly blink ou...
