Summer solstice 2024 marks the longest day in the Northern Hemisphere
The summer solstice, also known as the June solstice arrives June 20 at 4:51 p.m. EDT (2051 GMT), marking the longest day in the Northern Hemisphere.
Too young to be so cool: lessons from three neutron stars
ESA’s XMM-Newton and NASA’s Chandra spacecraft have detected three young neutron stars that are unusually cold for their age. By comparing their properties to different neutron star models, scientists conclude that the oddballs’ low temperatures disqualify around 75% of known models. This is a big step towards uncovering the one neutron star ‘equation of state’ that rules them all, with important implications for the fundamental laws of the Universe.
Scientists spot hidden companions of bright stars
Photographing faint objects close to bright stars is incredibly difficult. Yet, by combining data from ESA's Gaia space telescope with ESO’s GRAVITY instrument on the ground, scientists managed just that. They took the first pictures of so far unseen dim companions of eight luminous stars. The technique unlocks the tantalising possibility to capture images of planets orbiting close to their host stars.
Perseverance Found Some Strange Rocks. What Will They Tell Us?
NASA’s Perseverance Rover has left Mount Washburn behind and arrived at its next destination, Bright Angel. It found an unusual type of rock there that scientists are calling ‘popcorn rock.’ The odd rock is more evidence that water was once present in Jezero Crater.
Marsquakes Can Help Us Find Water on the Red Planet
Earth is a seismically active planet, and scientists have figured out how to use seismic waves from Earthquakes to probe its interior. We even use artificially created seismic waves to identify underground petroleum-bearing formations. When the InSIGHT (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) lander was sent to Mars, it sensed Marsquakes to learn more bout the planet’s interior.
Drone racing prepares neural-network AI for space
Drones are being raced against the clock at Delft University of Technology’s ‘Cyber Zoo’ to test the performance of neural-network-based AI control systems planned for next-generation space missions.

The speed of sound on Mars is constantly changing, study finds
New research shows that the speed of sound on Mars varies considerably by location and temperature. The findings could help scientists understand sounds picked up by Martian rovers, as well as make future crewed ventures safer.
If We Want To Find Life-Supporting Worlds, We Should Focus on Small Planets With Large Moons
There’s no perfect way of doing anything, including searching for exoplanets. Every planet-hunting method has some type of bias. We’ve found most exoplanets using the transit method, which is biased toward larger planets. Larger planets closer to their stars block more light, meaning we detect large planets transiting in front of their stars more readily than we detect small ones.
June solstice 2024 brings changing seasons to Earth on June 20 — What to know
Summer will officially arrive in the Northern Hemisphere on Thursday (June 20) at 4:51 p.m. EDT (2051 GMT) — the June Solstice. Here's what you need to know.
The 1st 'major lunar standstill' in more than 18 years is about to occur. Here's how to see it
A major lunar standstill is about to occur. The phenomenon happens every 18.6 years when the moon rises and sets at its most extreme points on the horizon, while also climbing to its highest and lowest point in the sky.
The Earliest Merging Quasars Ever Seen
Studying the history of science shows how often serendipity plays a role in some of the most important discoveries. Sometimes, the stories are apocryphal, like Newton getting hit on the head with an apple. But sometimes, there’s an element of truth to them. That was the case for a new discovery of the oldest pair of merging quasars ever discovered – and it all started with a pair of red blots on a picture.
327th ESA Council : Media information session at ESA HQ

ESA Director General Josef Aschbacher and ESA Council Chair Renato Krpoun brief journalists on decisions taken at the ESA Council meeting held in Paris on 18 and 19 June 2024.
A massive black hole may be 'waking up' in a nearby galaxy
Astronomers have, for the first time, spotted a black hole in a nearby galaxy waking up from a deep slumber.
'ESA Space Bricks' landing at Lego Stores could help build real Artemis moon base
Scientists found the building bricks for moon bases in the toy store, and you can see them there, too. ESA researchers discovered more than inspiration from Lego while working on Artemis structures.
GOES-U satellite launch this month will bring a solar activity monitor to space
Just like with other tools, the more a coronagraph ages, the less reliable it gets. So, next month, NOAA's GOES-U will take to space a brand-new coronagraph which will provide clearer images of the sun's activity.

China selects 4th batch of astronaut candidates as part of 2030 moon landing goal
China has selected 10 new astronauts for training as part of its goal to put a crew on the moon by 2030, the country's human spaceflight agency announced last week.
SpaceX launches 20 Starlink satellites from California
SpaceX launched 20 of its Starlink satellites from California on Tuesday night (June 18), ending a 10-day spaceflight drought for the company.
Hubble's Back, but Only Using One Gyro
The Hubble Space Telescope has experienced ongoing problems with one of its three remaining gyroscopes, so NASA has decided to shift the telescope into single gyro mode. While the venerable space telescope has now returned to daily science operations, single gyro mode means Hubble will only use one gyro to maintain a lock on its target. This will slow its slew time and decrease some of its scientific output. But this plan increases the overall lifetime of the 34-year-old telescope, keeping one gyro in reserve. NASA is also troubleshooting the malfunctioning gyro, hoping to return it online.
