What Telescope Will Be Needed to See the First Stars in the Universe? The Ultimately Large Telescope

New results from the NASA/ESA Hubble Space Telescope suggest the formation of the first stars and galaxies in the early Universe took place sooner than previously thought. A European team of astronomers have found no evidence of the first generation of stars, known as Population III stars, when the Universe was less than one billion years old.

The oldest stars in the Universe are cloaked in darkness. Their redshift is so high, we can only wonder about them. The James Webb Space Telescope will be our most effective telescope for observing the very early Universe, and should observe out to z = 15. But even it has limitations.

To observe the Universe’s very first stars, we need a bigger telescope. The Ultimately Large Telescope.

The Moon Might Be More Metal-Rich Than We Thought

A new study shows that the Moon is more metal-rich than previously thought. That has some far-reaching implications for our understanding of the Moon’s formation. If their results are solid, it means that we may need to re-think the giant impact hypothesis for the formation of the Moon.

Do We Now Understand Why the Moon’s Near and Far Sides Look So Dramatically Different?

We intend to explore the Moon, use its resources, and use it as a jumping-off point for missions deeper into the Solar System. For that we need a Lunar GPS. Image Credit: NASA

The Moon is easily the most well-studied object in the Solar System, (other than Earth, of course.) But it still holds some puzzles for scientists. Why, for instance, is one side of the Moon so different from the other?

Last Year’s Total Solar Eclipse on Earth, Seen From the Moon

On July 2, 2019, the Moon cast its shadow on the surface of the Earth. This time, the shadow’s path travelled across the South Pacific Ocean. It also passed over some of Argentina and Chile. For surface dwellers in the path, the Moon briefly blocked the Sun, turning night into day.

But for one “eye” in orbit around the Moon, the view was different. A camera on a tiny satellite watched as the circular shadow of the Moon moved over the Earth’s surface.

Hilarious Supercut of Astronauts Falling on the Moon

The Apollo astronauts walked on the Moon, yes. But they also hopped, bounded, and shuffled. And sometimes they fell, spectacularly. That caused a lot of consternation back on the Earth, especially for the engineers who designed the Apollo spacesuits.

Want to Mine Ice on the Moon? Scientists Create a Map for Where to Start

The first lunar maps consisted of simply the best images of the Moon from Earth-based telescopes, which were converted to provide necessary information for the Apollo astronauts.

But whenever the next lunar explorers arrive, they’ll have incredibly detailed topographic maps of the Moon’s surface, thanks to the high-resolution cameras and instruments on board satellites like the Lunar Reconnaissance Orbiter. LRO’s Lunar Orbiter Laser Altimeter (LOLA) zaps the Moon an incredible 140 times every second, measuring the ups and downs, nooks and crannies on the lunar surface to an accuracy within four inches.

This Laser Powered Rover Could Stay in the Shadows on the Moon and Continue to Explore

The craters on the Moon’s poles are in permanent shadow. But they’re also intriguing locations, due to deposits of water ice and other materials. The ESA is developing the idea for a rover that can explore these areas with power provided by lasers.

India’s Chandrayaan 2 is Creating the Highest Resolution Map We Have of the Moon

The Chandrayaan-2 lander, Vikram, attempted a landing September 7th (Friday the 6th in the United States), on a small patch of lunar highland smooth plains between Simpelius N and Manzinus C craters. Unfortunately the landing was not successful and location of the spacecraft has not been announced. The scene above was captured from an LROC Quickmap fly-around of the site, image width is about 150 kilometers across the center [NASA/GSFC/Arizona State University].

India’s space organization, ISRO, launched Chandrayaan 2 to the Moon last year in July. While its lander Vikram crashed on the lunar surface on September 7, the Chandrayaan 2 orbiter continues to orbit the Moon.

Comparing Mountains on the Moon to the Earth’s Peaks

NASA’s Artemis Program is planning to land astronauts on the Moon’s south pole. To prepare for this, NASA’s Solar System Exploration Research Virtual Institute (SSERVI) is creating the Lunar South Pole Atlas (LSPA). As part of that Atlas, NASA is mapping the topography of the region, including the mountains.

NASA is Planning to Build a Lunar Rover With a 1-Meter Drill to Search for Water Ice

Meet VIPER, NASA’s new lunar rover, equipped with a drill to probe the Moon’s surface and look for water ice. VIPER, or Volatiles Investigating Polar Exploration Rover, will carry a one-meter drill and will use it to map out water resources at the Moon’s south pole. It’s scheduled to be on the lunar surface by December 2023, one year later than it’s initial date.
