Watch NASA astronaut Loral O'Hara, two Russians launch to ISS today
NASA astronaut Loral O'Hara and two Russian cosmonauts will launch toward the ISS today (Sept. 15.) After they settle in, a crew on board for a year will return home.
Alien mummies in Mexico? NASA's UFO study team says don't bet on it
Lawmakers in Mexico heard testimony this week about the presence of alien life on Earth that included two "corpses of extraterrestrials." NASA's UAP study team isn't so sure.
This Week's Sky at a Glance, September 15 – 24
Comet Nishimura shines at its brightest... but don't be disappointed, we warned you. Meanwhile Jupiter joins Saturn as an evening light, and the Little Dipper dumps water into the Big Dipper.

SpaceX could get license for 2nd Starship launch in October, FAA says
SpaceX may get approval for its second-ever Starship launch sometime next month, according to an official with the U.S. Federal Aviation Administration.
Stunning James Webb Space Telescope image shows young star blasting supersonic jets
NASA's James Webb Space Telescope captured stunning jets blasting out of a protostar, shedding light on the makeup of very young, sun-like stars.
The Moon's Southern Ice is Relatively Young
Around the Moon’s southern polar region lies the South Pole-Aitken Basin, the single-largest impact basin on the lunar surface. Within this basin, there are numerous permanently shadowed regions (PSRs) that are thought to have trapped water ice over time. These deposits are crucial to future missions like the Artemis Program that will lead to the creation of permanent infrastructure. This water ice will supply crews with a steady source of water for drinking and irrigation and the means for chemically producing oxygen gas and rocket fuel.
Our universe holds more 'spectacular' polar ring galaxies than once thought, scientists say
Two previously discovered galaxies have been hiding strange perpendicular rings of stars and gas. These so-called polar ring galaxies may prove to be less rare in the universe than once thought.
Where to stand in Texas to see two solar eclipses in under six months
A small area of Texas will witness October's annular solar eclipse and April's total solar eclipse. Here's where you should stand to see them in all their glory.
Mini-Subs Could One Day Ply the Seas Under Europa’s Ice
The most promising places to look for life in the Solar System are in the ocean moons Europa and Enceladus. But all that warm, salty, potentially life-supporting water is under thick sheets of ice: up to 30 km thick on Europa and up to 40 km thick for Enceladus.
Space is 'more contested' than ever by world's militaries, US Space Force chief says
The Chief of Space Operations for the U.S. Space Force gave an ominous warning about how contested space is becoming as world superpowers continue to militarize Earth orbit.
SpaceX will launch 22 Starlink satellites early Sept. 15 — if Hurricane Lee doesn't interfere
SpaceX plans to launch 22 of its Starlink internet satellites just after midnight on Friday (Sept. 15), if the weather cooperates.
Hubble Space Telescope discovers 11-billion-year-old galaxy hidden in a quasar's glare
Astronomers have detected an 11-billion-year-old galaxy using the light it absorbs rather than the light it emits. This technique was necessary because the galaxy is being outshone by a nearby quasar.
Live Coverage: SpaceX keeping a weather eye on Hurricane Lee ahead of midnight Starlink launch
Live coverage will start here about one hour before launch
A 'Planet Nine' far from Earth could explain the odd behavior of icy bodies beyond Neptune
As the search for "Planet Nine" in the outer solar system continues, new research suggests there may be an Earth twin buried deep within the frozen waste of the Kuiper Belt beyond Neptune.
Following Up on Report, NASA Takes On a Bigger Role in UFO Research
In response to a newly released report from an independent panel, NASA says it has appointed a director in charge of research into UFOs — now known as unidentified anomalous phenomena, or UAPs — and will work with other agencies to widen the net for collecting UAP data.
ESA empowering retailers with exclusive B2B access
ESA is providing retailers with an exclusive opportunity to supply official ESA products through a new B2B platform.
If Neutron Stars Have Mountains, They Should Generate Gravitational Waves
A neutron star is 2 solar masses compressed into a ball only 12 kilometers wide. Its surface gravity is so immense it compresses atoms and molecules into raw nuclei and squeezes electrons into protons transforming them into neutrons. Given such immense pressures and densities, you might assume neutron stars have an almost perfectly smooth surface. But you’d be wrong because we know that neutron stars can have mountains.
Humanity's current space behavior 'unsustainable,' European Space Agency report warns
Greater efforts are needed to make valuable orbits sustainable, according to a new report from the European Space Agency.
